FIELD OF THE INVENTION

New insecticidal proteins, nucleotides, peptides, their expression inplants, methods of producing the peptides, new processes, productiontechniques, new peptides, new formulations, and combinations of new andknown organisms that produce greater yields than would be expected ofrelated peptides for the control of insects are described and claimed.

BACKGROUND

The global security of food produced by modern agriculture andhorticulture is challenged by insect pests. Farmers rely on insecticidesto suppress insect damage, yet commercial options for safe andfunctional insecticides available to farmers are diminishing through theremoval of dangerous chemicals from the marketplace and the evolution ofinsect strains that are resistant to all major classes of chemical andbiological insecticides. New insecticides are necessary for farmers tomaintain crop protection.

Insecticidal peptides are peptides that are toxic to their targets,usually insects or arachnids of some type, and often the peptides canhave arthropod origins such as from scorpions or spiders. They may bedelivered internally, for example by delivering the toxin directly tothe insect's gut or internal organs by injection or by inducing theinsect to consume the toxin from its food, for example an insect feedingupon a transgenic plant, and/or they may have the ability to inhibit thegrowth, impair the movement, or even kill an insect when the toxin isdelivered to the insect by spreading the toxin to locus inhabited by theinsect or to the insect's environment by spraying, or other means, andthen the insect comes into some form of contact with the peptide.

Insecticidal peptides however have enormous problems reaching thecommercial market and to date there have been few if any insecticidalpeptides approved and marketed for the commercial market, with onenotable exception, peptides derived from Bacillis thuringiensis or Bt.And now there is concern over rising insect resistance to Bt proteins.

Bt proteins, or Bt peptides, are effective insecticides used for cropprotection in the form of both plant incorporated protectants and foliarsprays. Commercial formulations of Bt proteins are widely used tocontrol insects at the larval stage. ICK peptides include many moleculesthat have insecticidal activity. Such ICK peptides are often toxic tonaturally occurring biological target species, usually insects orarachnids of some type. Often ICK peptides can have arthropod originssuch as the venoms of scorpions or spiders. Bt is the one and onlysource organism of commercially useful insecticidal peptides. Otherclasses and types of potential peptides have been identified, such asTrypsin modulating oostatic factor (TMOF) peptides. TMOF peptides haveto be delivered to their physiological site of action in various ways,and TMOF peptides have been identified as a potential larvicides, withgreat potential, see D. Borovsky, Journal of Experimental Biology 206,3869-3875, but like nearly all other insecticidal peptides, TMOF has notbeen commercialized or widely used by farmers and there are reasons forthis.

The ability to successfully produce insecticidal peptides on acommercial scale, with reproducible peptide formation and folding, at areasonable and economical price, can be challenging. The wide variety,unique properties and special nature of insecticidal peptides, combinedwith the huge variety of possible production techniques, can present anoverwhelming number of approaches to peptide application and production,but few, if any, are commercially successful.

There are several reasons why so few of the multitude insecticidalpeptides that have been identified have ever made it to market. First,most insecticidal peptides are either to delicate or not toxic enough tobe used commercially. Second, insecticidal peptides are difficult andcostly to produce commercially. Third, many insecticical peptidesquickly degrade and have a short half-life. Fourth, very fewinsecticidal peptides fold properly when then are expressed by a plant,thus they lose their toxicity in genetically modified organisms (GMOs).Fifth, most of the identified insecticidal peptides are blocked fromsystemic distribution in the insect and/or lose their toxic nature whenconsumed by insects. Bt proteins are an exception to this last problemand because they disrupt insect feeding they have been widely used.

Here we present several solutions to these major problems which haveprevented commercialization and wide spread use of insecticidalpeptides. In the first section, we describe how to create specialexpression cassettes and systems that allow plants to generate andexpress properly folded insecticidal peptides that retain their toxicityto insects.

In the second section, we describe how to make a relatively small changeto the composition of a peptide and in so doing dramatically increasethe rate and amount that can be made through fermentation. This processalso simultaneously lowers the cost of commercial industrial peptideproduction. This section teaches how a protein can be “converted” into adifferent, more cost effective peptide, that can be produced at higheryields and yet which surprisingly is just as toxic as before it wasconverted. In the third and final section, we describe how to combinedifferent classes of insectidical peptides such that they can operatetogether in a synergistic manner to dramatically change and increase thetoxicity and activity of the component peptides when compared to theirindividual components. This section also provides details and data tosupport our system, methods and peptide combinations and formulations todeal with a looming threat of the development and distribution of Btresistant insects. Bt resistant insects represent the next great threatto the global supply of food and we teach those skilled in the art howto meet and defeat this threat.

SUMMARY OF THE INVENTION

This invention describes how to produce toxic insecticidal peptides inplants so they fold properly when expressed by the plants. It describeshow to produce peptides in high yields in laboratory and commercialproduction environments using various vectors.

Wedisclose how to make and use combinations of CRIPS and PFIPS to kill andcontrol insects, even Bt resistant insects, at every low doses. Withoutbeing bound by theory, our understanding of Bt or Bacillus thuringiensispeptides and proteins, allows us to teach one ordinarily skilled in theart, to create novel methods, compositions, compounds (proteins andpeptides) and procedures to protect plants and control insects.

Section 1. Plant Incorporated Peptides or Plant Expressed Peptides“PIPs” and PEPs”

Plant-incorporated protectants, or “PIPs”, have presented one solutionto the insect pressure faced by farmers. Modern agriculture employsgenes from the Bacillus thuringiensis expressed as plant transgenicproteins to act as PIPs, but natural resistant insect strains have beendetected in the field and threaten this class. Additional PIPs withnovel modes of action need to be developed to manage the development ofresistance. A novel class of proteins with insecticidal activity havingthe potential to become PIPs, are called Cysteine Rich InsecticidalProteins (CRIPS) these proteins have 4, 6 or 8 cysteines and 2, 3 or 4disulfide bonds. One example of this class of compounds are said to beof the type called inhibitor cysteine knot (ICK) motif protein. ICKmotif proteins that have insecticidal activity have potential to beinsecticidal proteins and PIPs.

ICK motif proteins are a class of proteins with at least six cysteineresidues that form a specific ICK tertiary structure. Covalentcross-linking of the cysteine residues in the ICK motif proteins formdisulfide bridges that result in a tertiary structures that makes theprotein relatively resistant to proteases and sometimes to extremephysical conditions (pH, temperature, UV light, etc.), and confersactivity against ion channels, which might specific to insects. Many ICKmotif proteins have evolved in the venom of invertebrates andvertebrates that use the ICK motif proteins as a toxin to immobilize orkill their predators or prey. Such insecticidal peptides often havescorpion, spider and sometimes snake origins. In nature, toxic peptidescan be directed to the insect's gut or to internal organs by injection.In the case of a PIP, the delivery is usually via the insect'sconsumption of transgenic protein expressed in plant tissue. Upon thisconsumption of the toxin from its food, for example an insect feedingupon a transgenic plant, the ICK motif protein may have the ability toinhibit the growth, impair the movement, or even kill an insect.

Toxic peptides however often lose their toxicity when they are expressedin plants. Unless the ICK motif protein is expressed as a properlyfolded protein it cannot successfully protect a plant or crop frominsect damage. In some cases a plant expressed peptide will need to beactivated by cleavage within the insect or during expression process ina plant in order to be active. There is a need for methods and modifiedpeptides and nucleic acids that enable peptides to not only be expressedin a plant but to be expressed, folded properly and in some casescleaved properly such that the peptide retains its activity against aninsect even after expression in a plant. In this section we presentseveral ways to produce active peptides adapted for expression inplants.

Plant expressed inhibitory cysteine knot (ICK) motif proteins fromspiders and scorpions have been described (Khan et al, Transgenic Res.,2006, 15: 349-357; Hernandez-Campuzano et al, Toxicon. 2009 January;53(1):122-8.). We describe how to make plant expressed ICK motifproteins that are active and accumulate in plants to insecticidal doselevels. We show that prior descriptions of plant expressed ICK motifproteins were actually descriptions of inactive proteins that had losttheir natural toxicity. We describe methods to increase the efficacy ofthe plant expression, to increase the accumulation of plant expressedproteins and to dramatically increase the insecticidal activity of plantexpressed proteins. We describe how to induce the plant expressed ICKmotif proteins to enter the Endoplasmic Reticulum (ER) directed by anEndoplasmic Reticulum Signaling Protein (ERSP) in plant cells, in orderfor the correct covalent cross-linking of peptide disulfide bridgeswhich generate the essential tertiary ICK motif structure required forinsecticidal activity. We further describe the plant expressed,ER-trafficking ICK motif protein complex with a translationalstabilizing protein domain (STA) added in order to increase the size ofthe resulting ICK fusion protein which enhances peptide accumulation inthe plant. We further describe the plant expressed, ER-trafficking ICKmotif protein, with a translational stabilizing protein added as above,and with an intervening linker peptide (LINKER) added, the latter ofwhich may allow for potential cleavage and the recovery of the activeform of the ICK motif protein having insecticidal activity. We furtherdescribe the plant expressed polypeptide, which contains ER-traffickingICK motif protein domain with multiple ICK motif proteins separated byintervening linker peptides (LINKER), with an intervening linker peptideadded, with a translation stabilizing protein added, latter of whichallows the correctly folded ICK motif protein to accumulate in the plantto the insecticidal dose.

This invention describes the ICK motif protein with insecticidalactivity that are plant expressed and which can successfully protect aplant or crop from insect damage. The ICK motif protein expression ORFdescribed herein is a nucleotide which will enable the plant translatedpeptides to not only be expressed in a plant but also to be expressedand folded properly, and to be accumulated to the insecticidal dose inthe plant. An example of a protein expression ORF can be an ICK motifprotein expression ORF which is can be described below in equation styleand is shown in diagram style in the drawings or figures.

ersp-sta-(linker_(i)-crip_(j))_(N), orersp-(crip_(j)-linker_(i))_(N)-sta

The expression above is merely one example, and similar expressionscould be written for other types of CRIP expression ORFs, for example anICK expression ORF, could be written as:

ersp-sta-(linker_(i)-ick_(j))_(N), or ersp-(ick_(j)linker_(i))_(N)-sta

These expressions, equations or linear diagrams describe apolynucleotide open reading frame (ORF) for one type of CRIP, one whichexpresses the ICK motif protein complex, which can be described asERSP-STA-(LINKER_(I)—ICK_(J))_(N) or ERSP-(ICK_(J)-LINKER_(I))_(N)-STA,or as ERSP-STA-(L_(I)-ICK_(J))_(N) or ERSP-(ICK_(J)-L_(I))_(N)-STA,containing four possible peptide components with dash signs to separateeach component. In the diagrams above, the nucleotide component of erspis a polynucleotide segment encoding a plant endoplasmic reticulumtrafficking signal peptide (ERSP). The component of sta is apolynucleotide segment encoding a translation stabilizing protein (STA),which helps the accumulation of the ICK motif protein expressed inplants but may not be necessary in the ICK motif protein expression ORF.The component of linker_(i) is a polynucleotide segment encoding anintervening linker peptide (L OR LINKER) to separate the ICK motifproteins from each other and from the translation stabilizing protein,and the subscription “i” indicates that different types of linkerpeptides can be used in the CRIP or ICK motif protein expression ORF. Inthe case that sta is not used in the ICK motif protein expression ORF,ersp can directly be linked to the polynucleotide encoding an ICK motifprotein without a linker. The component of ick_(i) is a polynucleotidesegment encoding an ICK motif protein (ICK), and the subscription “j”indicates different ICK motif proteins; (linker_(i)-ick_(j))_(N)”indicates that the structure of the nucleotide encoding an interveninglinker peptide and an ICK motif protein can be repeated “N” times in thesame open reading frame in the same ICK motif protein expression ORF,where N can be any integrate number from 1 to 10. N can be from 1 to 10,specifically N can be 1, 2, 3, 4, or 5, and in some embodiments N is 6,7, 8, 9 or 10. The repeats may contain polynucleotide segments encodingdifferent intervening linkers (LINKER) and different ICK motif proteins.The different polynucleotide segments including the repeats within thesame ICK motif protein expression ORF are all within the sametranslation frame.

Any combination of the four principal components, ersp, sta, linker andcrip or ick as in the diagram of the ICK motif protein expression ORF,may be used to create a a PEP type ICK motif protein expression ORF aslong as a minimum of ersp and at least one copy of crip or ick are used.

I. The ERSP or Ersp Component of the PEPs.

The ICK motif protein expression ORF starts with an ersp at its 5′terminus. For the ICK motif protein to be properly folded and functionalwhen it is expressed from a transgenic plant, it must have an erspnucleotide fused in frame with the polynucleotide encoding an ICK motifprotein. During cellular translation process, translated ERSP can directthe ICK motif protein being translated to insert into the EndoplasmicReticulum (ER) of the plant cell by binding with a cellular componentcalled a signal-recognition particle. Within the ER the ERSP peptide iscleaved by signal peptidase and the ICK motif protein is released intothe ER, where the ICK motif protein is properly folded during thepost-translation modification process, for example, the formation ofdisulfide bonds. Without any additional retention protein signals, theprotein is transported through the ER to the Golgi apparatus, where itis finally secreted outside the plasma membrane and into the apoplasticspace. ICK motif protein can accumulate at apoplastic space efficientlyto reach the insecticidal dose in plants. FIG. 1 shows a representativediagram of a simple two component peptide or nucleotide composed of anERSP functionally linked to a ICK motif. The ICK could be a suitableCRIP. More complex proteins and polynucleotides utilizing ERSP arediagrammed in FIGS. 2-5 and these figures are further discussed in thediscussion of the STA or Translational Stabilizing Protein.

The ERSP peptide is at the N-terminal region of the plant translated ICKmotif protein complex and the ERSP portion is composed of about 3 to 60amino acids. In some embodiments it is 5 to 50 amino acids. In someembodiments it is 10 to 40 amino acids but most often is composed of 15to 20; 20 to 25; or 25 to 30 amino acids. The ERSP is a signal peptideso called because it directs the transportation of a protein. Signalpeptides may also be called targeting signals, signal sequences, transitpeptides, or localization signals. The signal peptides for ERtrafficking are often 15 to 30 amino acid residues in length and have atripartite organization, comprised of a core of hydrophobic residuesflanked by a positively charged aminoterminal and a polar, but unchargedcarboxyterminal region. (Zimmermann, et al, “Protein translocationacross the ER membrane”, Biochimica et Biohysica Acta, 2011, 1808:912-924).

Many ERSPs are known. Many plant ERSPs are known. It is NOT requiredthat the ERSP be derived from a plant ERSP, non-plant ERSPs will workwith the procedures described herein. Many plant ERSPs are however wellknown and we describe some plant derived ERSPs here. BAAS, for example,is derived from the plant, Hordeum vulgare, and has the amino acidsequence as follows:

-   -   MANKHLSLSLFLVLLGLSASLASG (SEQ ID NO: 4)

Plant ERSPs, which are selected from the genomic sequence for proteinsthat are known to be expressed and released into the apoplastic space ofplants, and a few examples are BAAS, carrot extensin, tobacco PR1. Thefollowing references provide further descriptions, and are incorporatedby reference herein in their entirety.

These references and othersteach and disclose the signal peptide that can be used in the methods,procedures and peptide, protein and nucleotide complexes and constructsdescribed herein.

II. The CRIP and ICK Motif Protein Component or Crip and Ick of thePEPs.

In our ICK motif protein expression ORF diagram, “ick” means apolynucleotide encoding an “ICK motif protein,” or “inhibitor cystineknot motif protein”, which is a 16 to 60 amino acid peptide with atleast 6 half-cysteine core amino acids having three disulfide bridges,wherein the 3 disulfide bridges are covalent bonds and of the sixhalf-cystine residues the covalent disulfide bonds are between the firstand fourth, the second and fifth, and the third and sixth half-cystines,of the six core half-cystine amino acids starting from the N-terminalamino acid. The ICK motif protein also comprises a beta-hairpinsecondary structure, normally composed of residues situated between thefourth and sixth core half-cysteines of the motif, the hairpin beingstabilized by the structural crosslinking provided by the motif's threedisulfide bonds. Note that additional cysteine/cysteine or half-cystineamino acids may be present within the inhibitor cysteine knot motif, asshown in FIG. 6. The CRIP or ICK motif can be repeated in order toincrease toxic peptide accumulation in the plant. See FIG. 4 and FIG. 5.This ability to repeat the CRIP or ICK motif, from 1 to 10 times andsometimes up to 15, 20 or 25 times is also shown in the equation likediagram of a CRIP or ICK protein expression ORF described herein asersp-sta-(linker_(i)-ick_(j))_(N), or ersp-(ick_(j)-linker_(i))_(N)-stawhere the number of repeating LINKER-ICK motifs is given by thesubscript number N and N is commonly 1-10 but can go even higher in someplants.

A similar expression like ersp-sta-(linker_(i)-ick_(j))_(N), orersp-(ick_(j)-linker_(i))_(N)-sta could be written and would describeother CRIP peptides. In this section an example of one expression ORF isone used to increase peptide expression in plants and is bestexemplified with an ICK protein. In the diagram above, a polynucleotideopen reading frame (ORF) which expresses an ICK motif protein complex,which can be described as ERSP-STA-(LINKER_(I)—ICK_(J))_(N) orERSP-(ICK_(J)-LINKER_(I))_(N)-STA, or as ERSP-STA-(L_(I)-ICK_(J))_(N) orERSP-(ICK_(J)-L_(I))_(N)-STA, containing four possible peptidecomponents with dash signs to separate the each component is used. Analternate method of showing this type of construct can be found in thefigures. In the diagram and the figures, the nucleotide component ofersp is a polynucleotide segment encoding a plant endoplasmic reticulumtrafficking signal peptide (ERSP). The component of sta is apolynucleotide segment encoding a translation stabilizing protein (STA),which helps the accumulation of the ICK motif protein expressed inplants but may not be necessary in the ICK motif protein expression ORF.The component of l_(i) is a polynucleotide segment encoding anintervening linker peptide (L OR LINKER) to separate the ICK motifproteins from each other and from the translation stabilizing protein,and the subscription “i” indicates that different types of linkerpeptides can be used in the ICK motif protein expression ORF. In thecase that sta is not used in the ICK motif protein expression ORF, erspcan directly be linked to the polynucleotide encoding an ICK motifprotein without a linker. The component of ick_(i) is a polynucleotidesegment encoding an ICK motif protein (ICK), and the subscription “j”indicates different ICK motif proteins; (linker_(i)-ick_(j))_(N)”indicates that the structure of the nucleotide encoding an interveninglinker peptide and an ICK motif protein can be repeated “N” times in thesame open reading frame in the same ICK motif protein expression ORF,where N can be any integrate number from 1 to 10, but can go even higherto 15, 20 and 25, these repeats may contain polynucleotide segmentsencoding different intervening linkers and different ICK or CRIP motifproteins. The different polynucleotide segments including the repeatswithin the same ICK or CRIP motif protein expression ORF are all withinthe same translation frame.

This motif is common in peptides isolated from the venom of numerousspecies. Invertebrate species include spiders, scorpions, cone snail,sea anemone etc., other examples are numerous, even snake venom has beenknown to have peptides having the ICK motif. An example within spidersthat we used is from a class of ACTX peptides from the Australian BlueMountains Funnel-web Spider, but the procedures described herein areuseful and may be applied to any protein with the ICK motif.

Examples of peptide toxins with the ICK motif can be found in thefollowing references. The N-type calcium channel blocker ω-Conotoxin wasreviewed by Lew, M. J. et al. “Structure-Function Relationships ofω-Conotoxin GVIA” Journal of Biological Chemistry, Vol. 272, No. 18,Issue of May 2, pp. 12014-12023, 1997.

From these and otherpublications, one skilled in the art should be able to readily identifyproteins and peptides having what we describe as the ICK motif, ICKmotif protein or the “inhibitor cystine knot motif.”

The ICK motif protein can be any protein with the ICK motif and isbetween 16 and 60 amino acids in length, with at least 6 cysteineresidues that create covalent cross-linking disulfide bonds in theproper order. See FIG. 6. Some ICK motif peptides have between 26-60amino acids in length. Some ICK motif proteins are between 16-48 aminoacids in length. Some ICK motif proteins are between 26-48 amino acidsin length. Some ICK motif proteins are between 30-44 amino acids inlength. ICK motif proteins with natural insecticidal activity arepreferred but ICK motif proteins with other types of activity such assalt and frost resistance are known to those skilled in the art and areclaimed herein. Examples of insecticidal ICK motif proteins include theACTX peptides and genes, and including all of the peptides and theircoding genes known as Magi6.

An example of a protein expression ORF could be an ICK motif proteinexpression ORF diagrammed below as:

ersp-sta-(linker_(i)-ick_(j))_(N), or ersp-(ick_(j)-linker_(i))_(N)-sta

A similar expression could be written for other CRIP peptides. In thissection this example of an expression ORF is one used to high peptideexpression and is best exemplified with an ICK protein. The diagramabove a polynucleotide open reading frame (ORF) which expresses an ICKmotif protein complex, which can be described asERSP-STA-(LINKER_(I)-ICK_(J))_(N) or ERSP-(ICK_(J)-LINKER_(I))_(N)-STA,or as ERSP-STA-(L_(I)-ICK_(J))_(N) or ERSP-(ICK_(J)-L_(I))_(N)-STA,containing four possible peptide components with dash signs to separatethe each component, In this diagram, the nucleotide component of ersp isa polynucleotide segment encoding a plant endoplasmic reticulumtrafficking signal peptide (ERSP). The component of sta is apolynucleotide segment encoding a translation stabilizing protein (STA),which helps the accumulation of the ICK motif protein expressed inplants but may not be necessary in the ICK motif protein expression ORF.The component of l_(i) is a polynucleotide segment encoding anintervening linker peptide (L OR LINKER) to separate the ICK motifproteins from each other and from the translation stabilizing protein,and the subscription “i” indicates that different types of linkerpeptides can be used in the ICK motif protein expression ORF. In thecase that sta is not used in the ICK motif protein expression ORF, erspcan directly be linked to the polynucleotide encoding an ICK motifprotein without a linker. The component of ick_(i) is a polynucleotidesegment encoding an ICK motif protein (ICK), and the subscription “j”indicates different ICK motif proteins; (linker_(i)-ick_(j))_(N)”indicates that the structure of the nucleotide encoding an interveninglinker peptide and an ICK motif protein can be repeated “N” times in thesame open reading frame in the same ICK motif protein expression ORF,where N can be any integrate number from 1 to 10, and the repeats maycontain polynucleotide segments encoding different intervening linkersand different ICK or CRIP motif proteins. The different polynucleotidesegments including the repeats within the same ICK or CRIP motif proteinexpression ORF are all within the same translation frame.

III. The Translational Stabilizing Protein Component, STA or Sta.

One of the ICK motif protein expression ORFs, ERSP-ICK, is sufficient toexpress a properly folded ICK motif peptide in the transformed plant,but in order for effective protection of a plant from pest damage, theplant expressed ICK motif protein needs to be accumulated to theinsecticidal level. With transformation of a properly constructed ICKmotif protein expression ORF, a transgenic plant can express andaccumulate greater amounts of the correctly folded ICK motif protein.When a plant accumulates greater amounts of properly folded toxicpeptides it can more easily resist or kill the insects that attack andeat the plants. The translational stabilizing protein can be used tosignificantly increase the accumulation of the toxic peptide in theplant and thus the potency of the PIP, especially when the PIP has atranslational stabilizing protein of its own. See variousrepresentations of how the STA may be used in expression ORFs in FIGS.2-5, and in various linear diagrams or equation like expressions usedbelow. The translational stabilizing protein can be a domain of anotherprotein or it can comprise an entire protein sequence. The translationalstabilizing protein is a protein with sufficient tertiary structure thatit can accumulate in a cell without being targeted by the cellularprocess of protein degradation. The protein can be between 5 and 50aa(e.g. another ICK-motif protein), 50 to 250aa (GNA), 250 to 750aa (e.g.chitinase) and 750 to 1500aa (e.g. enhancin).

In addition to FIGS. 2-5 the following linear diagram below describesone of the examples of the ICK motif protein expression ORF that encodesa stabilizing protein fused with ICK motif protein:

ersp-sta-l-ick

The protein, or protein domain can contain proteins that have no usefulcharacteristics other than translation stabilization, or they can haveother useful traits in addition to translational stabilization. Usefultraits can include: additional insecticidal activity, such as activitythat is destructive to the peritrophic membrane, activity that isdestructive to the gut wall, and/or activity that actively transportsthe ICK motif protein across the gut wall. One embodiment of thetranslational stabilizing protein can be a polymer of fusion proteinsinvolving ICK motif proteins. A specific example of a translationalstabilizing protein is provided here to illustrate the use of atranslational stabilizing protein. The example is not intended to limitthe disclosure or claims in any way. Useful translational stabilizingproteins are well known in the art, and any proteins of this type couldbe used as disclosed herein. Procedures for evaluating and testingproduction of peptides are both known in the art and described herein.One example of one translational stabilizing protein is SEQ ID NO:7, oneletter code, as follows:

ASKGE ELFTG VVPIL VELDG DVNGH KFSVS GEGEG DATYG KLTLK FICTT GKLPV PWPTLVTTFS YGVQC FSRYP DHMKR HDFFK SAMPE GYVQE RTISF KDDGN YKTRA EVKFE GDTLVNRIEL KGIDF KEDGN ILGHK LEYNY NSHNV YITAD KQKNG IKANF KIRHN IEDGS VQLADHYQQN TPIGD GPVLL PDNHY LSTQS ALSKD PNEKR DHMVL LEFVT AAGIT HGMDE LYK(SEQ ID NO: 7). Named “GFP.” The molecular weight is 26736.02 Daltons.

In some embodiments the STA can even be CRIP or ICK as shown in FIG. 5.In these embodiments there is no separate STA protein, the STA proteinis the same as the CRIP or ICK used. It could be the identical ICK thatis bound with the LINKER, or there could be different ICKs one typebound to the LINKER and the other type acting as the STA. Thesealternative arrangements are also discussed in the section on LINKERS.

IV. The Intervening Linker Peptide Component, LINKER, Linker, L or ifPolynucleotide: Linker or l of the PEPs

The ICK motif protein expression ORF described in this invention alsoincorporates polynucleotide sequences encoding intervening linkerpeptides between the polynucleotide sequences encoding the ICK motifprotein (ick) and the translational stabilizing protein (sta), orbetween polynucleotide sequences encoding multiple ICK motif proteinsdomain ((l-ick)_(N) or (ick-l)_(N)) if the expression ORF involvesmultiple ICK motif protein domain expression. The intervening linkerpeptides (LINKERS) separate the different parts of the expressed ICKmotif protein complex and help proper folding of the different parts ofthe complex during the expression process. In the expressed ICK motifprotein complex, different intervening linker peptides can be involvedto separate different functional domains. Various representations ofproteins with LINKERS are shown in (FIGS. 3-5.) The LINKER is attachedto a CRIP such as an ICK and this bivalent group can be repeated up to10 (N=1-10) and possibly even more than 10 times in order to facilitatethe accumulation of properly folded insecticidal peptide in the plantthat is to be protected.

The intervening linker peptide is usually between 1 and 30 amino acidsin length. It is not necessary an essential component in the expressedICK motif protein complex in plants. A cleavable linker peptide can bedesigned to the ICK motif protein expression ORF to release the properlyfolded ICK motif protein from the expressed ICK motif protein complex inthe transformed plant to improve the protection the ICK motif protein tothe plant from pest damage. One type of the intervening linker peptideis the plant cleavable linker peptide. This type of linker peptides canbe completely removed from the expressed ICK motif protein expressioncomplex during the post-translational expression process in the plantcells. Therefore the properly folded ICK motif protein linked by thistype of intervening linker peptides can be released in the plant cellsfrom the expressed ICK motif protein complex during thepost-translational expression process. Here we show numerous examples ofLINKERS.

Another type of the cleavable intervening linker peptide is notcleavable during the expression process in plants. However, it has aprotease cleavage site specific to serine, theronine, cysteine,aspartate proteases or metalloproteases. The type of cleavable linkerpeptide can be digested by proteases found in the insect andlepidopteran gut environment and/or the insect hemolymph andlepidopteran hemolymph environment to release the ICK motif protein inthe insect gut or hemolymph. Here we show numerous examples of LINKERSThese linkers are presented as examples only and should not beconsidered limiting the invention. Using the information taught by thisdisclosure it should be a matter of routine for one skilled in the artto make or find other examples of LINKERS that will be useful in thisinvention.

An example of a cleavable type of intervening linker that illustratesthe invention is listed in SEQ ID NO: 1, but cleavable linkers are notlimited to this example. SEQ ID NO: 1 (one letter code) is IGER and herewe name it “IGER.” The molecular weight of this intervening linker orLINKER is 473.53 Daltons.

An intervening linker peptide (LINKER) can also be one without any typeof protease cleavage site, i.e. an uncleavable intervening linkerpeptide. An example of this is the linker ETMFKHGL (SEQ ID NO. 3).

Other examples of intervening linker peptides can be found in thefollowing references, which are incorporated by reference herein intheir entirety: A plant expressed serine proteinase inhibitor precursorwas found to contain five homogeneous protein inhibitors separated bysix same linker peptides in Heath et al. “Characterization of theprotease processing sites in a multidomain proteinase inhibitorprecursor from Nicotiana alata” European Journal of Biochemistry, 1995;230: 250-257. A comparison of the folding behavior of green fluorescentproteins through six different linkers is explored in Chang, H.

The ICK motif protein expression ORF described above can be cloned intoany plant expression vector for the ICK motif protein expression inplant transiently or stably.

Transient Plant Expression Systems

Transient plant expression systems can be used to promptly optimize thestructure of the ICK motif protein expression ORF for some specific ICKmotif protein expression in plants, including the necessity of somecomponents, codon optimization of some components, optimization of theorder of each components, etc. A transient plant expression vector isoften derived from a plant virus genome. Plant virus vectors provideadvantages in quick and high level of foreign gene expression in plantdue to the infection nature of plant viruses. The full length of theplant viral genome can be used as a vector, but often a viral componentis deleted, for example the coat protein, and transgenic ORFs aresubcloned in that place. The ICK motif protein expression ORF can besubcloned into such a site to create a viral vector. These viral vectorscan be introduced into plant mechanically since they are infectiousthemselves, for example through plant wound, spray-on etc. They can alsobe transformed into plants by agroinfection by cloning the virus vectorinto the T-DNA of the crown gall bacterium, Agrobacterium tumefaciens,or the hairy root bacterium, Agrobacterium rhizogenes. The expression ofthe ICK motif protein in this vector is controlled by the replication ofthe RNA virus, and the virus translation to mRNA for replication iscontrolled by a strong viral promoter, for example, 35S promoter fromCauliflower mosaic virus. Viral vectors with ICK motif proteinexpression ORF are usually cloned into T-DNA region in a binary vectorthat can replicate itself in both E. coli strains and Agrobacteriumstrains. The transient transformation of a plant can be done byinfiltration of the plant leaves with the Agrobacterium cells whichcontain the viral vector for ICK motif protein expression. In thetransient transformed plant, it is common for the foreign proteinexpression to be ceased in a short period of time due to thepost-transcriptional gene silencing (PTGS). Sometimes a PTGS suppressingprotein gene is necessary to be co-transformed into the planttransiently with the same type of viral vector that drives theexpression of with the ICK motif protein expression ORF. This improvesand extends the expression of the ICK motif protein in the plant. Themost commonly used PTGS suppressing protein is P19 protein discoveredfrom tomato bushy stunt virus (TBSV).

A demonstration of transient plant expression can be found in FIG. 7.

FIG. 7 shows transiently expressed Plant Transgenic Protein. In FIG. 7reports the relative accumulation of the ICK proteins compared to the %TSP, as detected by ELISA. There are four variations of ICK expressionORFs in FIG. 7 that illustrate the necessity of the ERSP to get properfolding of the ICK and the STA to get accumulation of the protein. Bar Areports a FECT expression system expressing SEQ ID NO: 8 the omegapeptide (ICK) without any fusions. Bar B reports a TRBO expressionsystem expressing SEQ ID NO: 9 a BAAS ERSP fused to the omega peptide(ICK). Bar C reports a FECT expression system expressing SEQ ID NO: 10 aGFP (STA) fused to IGER (Linker) fused to Hybrid toxin (ICK). Bar Dreports a FECT expression system expressing SEQ ID NO:11 a BAAS (ERSP)fused to a GFP (STA) fused to IGER (Linker) fused to Hybrid toxin (ICK).The detection levels for Bar A and B show negligible protein detection.In Bar A this is likely due to no proper folding of the ICK which occursin the ER and in Bar B this is likely due to proper folding but noaccumulation due to the lack of a STA. There are detectable levels inBars C and D. When the experiment for Bar C [(SEQ ID NO: 10) a GFP (STA)fused to IGER (Linker) fused to Hybrid toxin (ICK)] was performed therewas a high level of GFP fluorescence detected (data not shown)indicating much of the TSP was the fusion protein, however, when theELISA was performed only 0.01% of the TSP was detected, and this islikely due to the lack of proper folding which did not occur as thisprotein was not targeted to the ER where folding occurs. The antibodiesused in ELISA only detect the tertiary structure of a properly foldedprotein. When the experiment for Bar D [SEQ ID NO:11 a BAAS (ERSP) fusedto a GFP (STA) fused to IGER (Linker) fused to Hybrid toxin (ICK)] wasperformed there was some GFP fluorescence detected and an accumulation0.1% of the TSP the ICK peptide fused to GFP. When the data for Bars A,B, C and D is taken together it is apparent that an ERSP in the ICKexpression ORF is required to get proper folding and to increase theaccumulation of the peptide a STA is required.

Integration of Protein Expression ORF into Plant Genome Using StablePlant Transformation Technology

The ICK motif protein expression ORF can also be integrated into plantgenome using stable plant transformation technology, and therefore ICKmotif proteins can be stably expressed in plants and protect thetransformed plants from generation to generation. For the stabletransformation of plants, the ICK motif protein expression vector can becircular or linear. A few critical components must be included in thevector DNA. The ICK motif protein expression ORF for stable planttransformation should be carefully designed for optimal expression inplants based on the study in the transient plant expression as describedabove. The expression of ICK motif protein is usually controlled by apromoter that promoters transcription in some of all cells of thetransgenic plant. The promoter can be a strong plant viral promoter, forexample, the constitutive 35S promoter from Cauliflower Mosaic Virus(CaMV); it also can be a strong plant promoter, for example, thehydroperoxide lyase promoter (pHPL) from Arabidopsis thaliana; theGlycine max polyubiquitin (Gmubi) promoter from soybean; the ubiquitinpromoters from different plant species (rice, corn, potato, etc.), etc.A plant transcriptional terminator often occurs after the stop codon ofthe ORF to halt the RNA polymerase and transcription of the mRNA. Toevaluate the ICK motif protein expression, a reporter gene can beincluded in the ICK motif protein expression vector, for example,beta-glucuronidase gene (GUS) for GUS straining assay, green fluorescentprotein (GFP) gene for green fluorescence detection under UV light, etc.For selection of transformed plants, a selection marker gene is usuallyincluded in the ICK motif protein expression vector. The marker geneexpression product can provide the transformed plant with resistance tospecific antibiotics, for example, kanamycin, hygromycin, etc., orspecific herbicide, for example, glyphosate etc. If agroinfectiontechnology is adopted for plant transformation, T-DNA left border andright border sequences are also included in the ICK motif proteinexpression vector to transport the T-DNA portion into the plant. Theconstructed ICK motif protein expression vector can be transform intoplant cells or tissues using many transformation technologies.Agroinfection is a very popular way to transform a plant using anAgrobacterium tumefaciens strain or an Agrobacterium rhizogenes strain.Particle bombardment (also called Gene Gun, or Biolistics) technology isalso very commonly used for plant transformation. Other less commonlyused transformation methods include tissue electroportation, siliconcarbide whiskers, direct injection of DNA, etc. After transformation,the transformed plant cells or tissues placed on plant regenerationmedia to regenerate successfully transformed plant cells or tissues intotransgenic plants. The evaluation of the integration and expression ofthe ICK motif protein expression ORF in the transformed plant can beperformed as follows.

Evaluation of a Transformed Plant

Evaluation of a transformed plant can be done in DNA level, RNA leveland protein level. A stably transformed plant can be evaluated at all ofthese levels and a transiently transformed plant is usually onlyevaluated at protein level. To ensure that the ICK expression motifprotein expression ORF integrates into the genome of a stablytransformed plant, the genomic DNA can be extracted from the stablytransformed plant tissues for the PCR evaluation or the Southern blotapplication. The expression of the ICK motif protein in the stablytransformed plant can be evaluated in RNA level, i.e. the total mRNA canbe extracted from the transformed plant tissues and the northern blottechnique and the RT-PCR technology can applied to evaluate the mRNAlevel of the ICK motif protein qualitatively or quantitatively. Theexpression of the ICK motif protein in the transformed plant can also beevaluated in protein level directly. There are many ways to evaluate theICK motif protein expressed in a transformed plant. If a reporter geneis transformed into the plant along with the ICK motif proteinexpression ORF, the reporter gene assay can be performed to initiallyevaluate the expression of the transformed ICK motif protein expressionORF, for example, GUS straining assay for GUS reporter gene expression,green fluorescence detection assay for GFP reporter gene expression,luciferase assay for luciferase reporter gene expression, etc. Moreover,the total expressed protein can be extracted from the transformed planttissues for the direct evaluation of the expression of the ICK motifprotein in the transformed plants. The extracted total expressed proteinsample can be used in Bradford assay to evaluate the total protein levelin the sample. Analytical HPLC chromatography technology, Western blottechnique, or iELISA assay can be adopted to qualitatively orquantitatively evaluate the ICK motif protein in the extracted totalprotein sample from the transformed plant tissues. The ICK motif proteinexpression can also be evaluated by using the extracted total proteinsample from the transformed plant tissues in an insect bioassay.Finally, the transformed plant tissue or the whole transformed plant canbe tested in insect bioassays to evaluate the ICK motif proteinexpression and its protection for the plant.

Example 1 Expression Comparison Between Two Transient Plant ExpressionSystems

The transient plant transformation technologies were adopted to promptlyoptimize the ICK motif protein expression ORF for plant expression.Agroinfection technology with a plant viral vector has been used herefor the transient plant transformation due to its high efficiency,easiness and inexpensiveness. Two viral transient plant expressionsystems were evaluated here for the ICK motif protein expression inplants. One was a tobacco mosaic virus overexpression system (TRBO,Lindbo J A, Plant Physiology, 2007, V145: 1232-1240.). The TRBO DNAvector has a T-DNA region for agroinfection, which contains a CaMV 35Spromoter that drives expression of the tobacco mosaic virus RNA withoutthe gene encoding the viral coating protein. The other viral transientplant expression system was the FECT expression system (Liu Z & KearneyC M, BMC Biotechnology, 2010, 10:88). The FECT vector also contains aT-DNA region for agroinfection, which contains a CaMV 35S promoter thatdrives the expression of the foxtail mosaic virus RNA without the genesencoding the viral coating protein and the triple gene block. Bothexpression systems use the “disarmed” virus genome, therefore viralplant to plant transmission can be effectively prevented. To efficientlyexpress the introduced heterologous gene, the FECT expression systemadditionally needs to co-express P19, a RNA silencing suppressor proteinfrom tomato bushy stunt virus, to prevent the post-transcriptional genesilencing (PTGS) of the introduced T-DNA. (The TRBO expression systemdoes not need co-expression of P19). The two transient plant expressionsystems were tested and compared by transient expression of ICK motifprotein in Tobacco (Nicotiana benthamiana) as described below.

The ICK motif protein expression ORF was designed to encode a series oftranslationally fused structural motifs that can be described asfollows: N′-ERSP-Sta-L-ICK-C′. Here the ICK motif protein for expressionis U-ACTX-Hv1a, which has the following amino acid sequence (N′ to C′,one letter code):

(SEQ ID NO: 12) QYCVPVDQPCSLNTQPCCDDATCTQERNENGHTVYYCRAThe ERSP motif used here is the Barley Alpha-Amylase Signal peptide(BAAS), which comprises of 24 Amino acids as shown below (N′ to C′, oneletter code):

(SEQ ID NO: 1) IGERAccording to the ICK motif expression ORF formula, this specific ICKexpression ORF can be described as BAAS-GFP-IGER-Hybrid, or BGIH. TheBGIH ORF was chemically synthesized by adding Pac I restriction site atits 5′ terminus and Avr II restriction site at its 3′ terminus. Thesequence of the synthetic BGIH is below:

The BGIH ORF was cloned into the Pac I and Avr II restriction sites ofthe FECT expression vector to create a BGIH expression vector for theFECT transient plant expression system (pFECT-BGIH). To maximize BGIHexpression in the FECT expression system, a FECT vector expressing theRNA silencing suppressor protein P19 (pFECT-P19) was generated forco-transformation. To create a BGIH expression vector for TRBO transientplant expression system, a routine PCR procedure was performed to add aNot I restriction site to the 3′ terminus of the BGIH ORF describedabove. The new BGIH ORF was then cloned into Pac I and Not I restrictionsites of the TRBO expression vector to create a BGIH expression vectorfor the TRBO transient plant expression system (pTRBO-BGIH).

An Agrobacterium tumefaciens strain, GV3101, was used for the transientexpression of BGIH in tobacoo leaves by the FECT and TRBO expressionsystems. To make competent GV3101 cells the following procedure wasperformed: an overnight culture of GV3101 was used to inoculate 200 mLLuria-Bertani (LB) medium. The cells were then allowed to grow to logphase with OD600 between 0.5 and 0.8. Then the cells were pelleted bycentrifugation at 5000 rpm for 10 minutes at 4° C. The cells were thenwashed once with 10 mL prechilled TE buffer (Tris-HCl 10 mM, EDTA 1 mM,018.0), and then resuspended into 20 mL LB medium. The GV3101 cellresuspension was then aliquoted in 250 μl fractions into 1.5 mLmicrotubes. The aliquots were then snap-frozen in liquid nitrogen andstored at −80° C. freezer for future transformation.

The pFECT-BGIH and pTRBO-BGIH vectors were then transformed into thecompetent GV3101 cells using a freeze-thaw method as follows: the storedcompetent GV3101 cells were thawed on ice and then mixed with 1-5 μgpure DNA (pFECT-BGIH or pTRBO-BGIH vector). The cell-DNA mixture wasthen kept on ice for 5 minutes, then transferred to −80° C. for 5minutes, and then incubated in a 37° C. water bath for 5 minutes. Thefreeze-thaw treated cells were then diluted into 1 mL LB medium andshaken on a rocking table for 2-4 hours at room temperature. A 200 μLaliquot of the cell-DNA mixture was then spread onto LB agar plates withthe appropriate antibiotics (10 μg/mL rifampicin, 25 μg/mL gentamycin,and 50 μg/mL kanamycin were used for both pFECT-BGIH transformation andpTRBO-BGIH transformation) and incubated at 28° C. for two days.Resulting transformant colonies were then picked and culture in 6 mLaliquots of LB medium with the appropriate antibiotics for transformedDNA analysis and making glycerol stocks of the transformed GV3101 cells.

The transient transformation of tobacco leaves was performed using leafinjection with a 3 mL syringe without needle. The transformed GV3101cells were streaked onto an LB plate with the appropriate antibiotics(as described above) and incubated at 28° C. for two days. A colony oftransformed GV3101 cells was inoculated to 5 ml of LB-MESA medium (LBmedia supplemented with 10 mM MES, 20 μM acetosyringone) and the sameantibiotics described above, and grown overnight at 28° C. The cells ofthe overnight culture were collected by centrifugation at 5000 rpm for10 minutes and resuspended in the induction medium (10 mM MES, 10 mMMgCl2, 100 μM acetosyringone) at a final OD600 of 1.0. The cells werethen incubated in the induction medium for 2 hour to overnight at roomtemperature and were then ready for transient transformation of tobaccoleaves. The treated cells were infiltrated into the underside ofattached leaves of Nicotiana benthamiana plants by injection, using a 3mL syringe without a needle attached. For the FECT transienttransformation, the pFECT-BGIH transformed GV3101 cells and pFECT-P19transformed GV3101 cells were mixed together in equal amounts forinfiltration of tobacco leaves by injection with a 3 mL syringe. For theTRBO transient transformation, only pTRBO-BGIH transformed GV3101 cellswere infiltrated into tobacco leaves. The ICK motif protein expressionin tobacco leaves was evaluated at 6-8 days post-infiltration.

The BGIH expression ORF contains a fusion protein of GFP (STA) andU-ACTX-Hv1a (ICK) with an IGER (SEQ ID NO: 1) linker peptide (LINKER)between them. As shown in FIG. 3, the green fluorescence of theexpressed GFP portion of the transgenes was detected under U.V. light intobacco leaves transformed with both the FECT and TRBO vectors.Interestingly, green fluorescence appeared evenly distributed in theFECT vector transformed tobacco leaves (with the exception of thevascular tissues), whereas green fluorescence in the TRBO vectortransformed tobacco leaves appeared to accumulate in the vasculartissues which is due to TRBO retaining its viral movement protein andFECT not.

To quantitatively evaluate the ICK motif protein expression, theexpressed proteins in the transformed tobacco leaves were extracted byfollowing the procedure described here. 100 mg disks of transformed leaftissue were collected by punching leaves with the large opening of a1000 μL pipette tip. The collected leaf tissue was place into a 2 mLmicrotube with 5/32″ diameter stainless steel grinding balls, and frozenin −80° C. for 1 hour, and then homogenized using a Troemner-TalboysHigh Throughput Homogenizer. 750 μL ice-cold TSP-SEI extractionsolutions (sodium phosphate solution 50 mM, 1:100 diluted proteaseinhibitor cocktail, EDTA 1 mM, DIECA 10 mM, PVPP 8%, pH 7.0) was addedinto the tube and vortexed. The microtube was then left still at roomtemperature for 15 minutes and then centrifuged at 16,000 g for 15minutes at 4° C. 100 μL of the resulting supernatant was taken andloaded into pre-Sephadex G-50-packed column in 0.45 μm MilliporeMultiScreen filter microtiter plate with empty receiving Costarmicrotiter plate on bottom. The microtiter plates were then centrifugedat 800 g for 2 minutes at 4° C. The resulting filtrate solution, hereincalled total soluble protein extract (TSP extract) of the tobaccoleaves, was ready for the quantitative analysis.

The total soluble protein concentration of the TSP extract was estimatedusing Pierce Coomassie Plus protein assay. BSA protein standards withknown concentrations were used to generate a protein quantificaationstandard curve. 2 μL of each TSP extract was mixed into 200 μL of thechromogenic reagent (CPPA reagent) of the Coomassie Plus protein assaykits and let react for 10 minutes. The chromogenic reaction was thenevaluated by reading OD595 using a SpectroMax-M2 plate reader usingSoftMax Pro as control software. The concentrations of total solubleproteins were 0.788±0.20 μg/μL and 0.533±0.03 μg/μL in the TSP extractfrom FECT-BGIH expression leaves and TRBO-BGIH expression leavesrespectively. These results were used for the calculation of percentageof the expressed U-ACTX-Hv1a in the TSP (% TSP) in the iELISA assay.

Indirect ELISA (iELISA) assay was performed as follows to quantitativelyevaluate the ICK motif protein in the tobacco leaves transientlytransformed with the FECT and TRBO expression systems. 5 μL of the leafTSP extract was diluted into 95 μL CB2 solution (ImmunochemistryTechnologies) in the well of an Immulon 2HD 96-well plate, with serialdilutions performed as necessary. Leaf proteins were from the extractsamples were then allowed to coat the well walls for 3 hours in the darkat room temperature, and then the CB2 solution was removed, and eachwell was washed twice with 200 μL PBS (Gibco). 150 μL blocking solution(Block BSA in PBS with 5% non-fat dry milk) was then added into eachwell and incubated for 1 hour, in the dark, at room temperature. Afterthe removal of the blocking solution and a PBS wash of the wells, 100 μLof rabbit anti-U-ACTX-Hv1a antibody (primary antibody) (1:250 dilutionin blocking solution) was added to each well and incubated for 1 hour inthe dark at room temperature. The primary antibody was then removed andeach well was washed with PBS 4 times. Then 100 μL of HRP-conjugatedgoat anti-rabbit antibody (secondary antibody, used at 1:1000 dilutionin the blocking solution) was added into each well and incubated for 1hour in the dark at room temperature. After removal of the secondaryantibody and wash of the wells with PBS, 100 μL substrate solution (a1:1 mixture of ABTS peroxidase substrate solution A and solution B, KPL)was added to each well, and the chromogenic reaction was allowed to gountil sufficient color development was apparent. Then 100 μL ofperoxidase stop solution was added to each well to stop the reaction.The light absorbance of each reaction mixture in the plate was read at405 nm using a SpectroMax-M2 plate reader, with SoftMax Pro used ascontrol software. Serially diluted known concentrations of pureU-ACTX-Hv1a samples were treated in the same manner as described abovein the iELISA assay to generate a mass-absorbance standard curve forquantities analysis. The expressed U-ACTX-Hv1a was detected by iELISA at3.09±1.83 ng/μL in the leaf TSP extracts from the FECT-BGIH transformedtobacco; and 3.56±0.74 ng/μL in the leaf TSP extract from the TRBO-BGIHtransformed tobacoo. Or the expressed U-ACTX-Hv1a is 0.40% total solubleprotein (% TSP) for FECT-BGIH transformants and 0.67% TSP in TRBO-BGIHtransformants.

In conclusion, both FECT and TRBO transient plant expression systems canbe used to express the ICK motif protein in plant. The ICK motif proteinexpression level in both systems is very close. However, the expressionin the FECT system distributes evenly in the agroinfiltrated leaves,whereas the expression in the TRBO system accumulates in the vasculartissue of the agroinfiltrated leaves.

Example 2 ICK Motif Protein Transient Expression in Tobacco Leaf withAccumulation at Different Subcellular Targets

Plant expressed ICK motif protein needs to accumulate to a certain levelin the plant to effectively protect the plant from insect damage. Theaccumulation level of the plant expressed ICK motif protein may beaffected by its final localization in the plant cells. In this example,we investigated the effects of different subcellular localizations ofthe plant expressed ICK motif protein on the protein's accumulationlevel in the plant (using the FECT transient plant expression system).Three subcellular targets were investigated in this example, plant cellwall apoplast (APO), the endoplasmic reticulum (ER) and the cytoplasm(CYTO).

The APO targeted ICK motif protein expression ORF was designed to encodea series of translationally fused structural motifs that can bedescribed as follows: N′-ERSP-Sta-L-ICK-C′. Again the ICK motif proteinin this study was U-ACTX-Hv1a, and the BGIH expression ORF in theexample 1 was used. The same vector as in the example 1, pFECT-BGIH, wasused here.

The CYTO targeted ICK motif protein expression ORF was designed toencode a series of translationally fused structural motifs that can bedescribed as follows: N′-Sta-L-ICK-C′. In this study, the DNA sequenceencoding the barley α-amylase signal peptide was removed from the BGIHexpression ORF and became the GIH expression ORF, whose open readingframe sequence is below:

The ER targeted ICK motif protein expression ORF was designed by addinga DNA sequence encoding the ER targeting signal peptide at the C′ end ofthe BGIH expression ORF which was named as BGIH-ER expression ORF. TheER targeting signal peptide used here has the following amino acidsequence (one letter code for amino acid):

All three vectors, pFECT-BGIH, pFECT-GIH and pFECT-BGIH-ER, weretransformed into the Agrobacterium strain, GV3101, and the resultingtransformed GV3101 cells were used for transient transformation into theleaves of Nicotiana benthamiana using the methods described inExample 1. All of the three expression ORFs should transiently express afusion protein, comprising GFP-fused U-ACTX-Hv1a with a trypsincleavable linker between the two structural domains.

After 6 days of transient tobacco transformation, the expression ofGFP-fused U-ACTX-Hv1a was examined initially by detection of greenfluorescence under UV light. Green fluorescence was detected at variouslevels in all of the transformed tobacco leaves. The transformed leaveswith CYTO targeted accumulation of GFP fused U-ACTX-Hv1a showed thestrongest green fluorescence, and those leaves with APO or ER targetedfusion protein accumulation showed weaker green fluorescence. Thus, theresults indicated that CYTO targeted expression may facilitate greateraccumulation of transgenic GFP fused U-ACTX-Hv1a protein than the APOand ER targeted expression in tobacco leaves. In three replications ofthis experiment, the transformed tobacco leaves with CYTO targetedexpression always showed green fluorescence similar to or stronger thanthat of the leaves with APO targeted expression, and the weakest greenfluorescence was detected in the tobacco leaves transformed with the ERtargeted constructs. These initial results indicated that CYTO targetedexpression may accumulate as much or more transgenic fusion protein thanAPO targeted expression, and that ER targeted expression yielded theleast accumulation.

Total soluble protein samples were extracted from tobacco leavestransformed with the different FECT vectors (protocol was described indetail in Example 1). Pierce Coomassie Plus protein assay was performedas in the description in Example 1 to determine the concentrations ofthe total soluble protein in the TSP extracts, yielding the followingconcentration estimates: 0.31±0.04 μg/μL, 0.31±0.03 μg/μL and 0.34±0.05μg/μL for APO targeted, CYTO targeted and ER targeted expressionsrespectively (N=3).

The indirect ELISA protocol was then performed using the TSP extracts asdescribed in Example 1 to quantitate the expression level of theU-ACTX-Hv1a protein as a percentage of total soluble protein (% TSP),yielding the following percentage estimates: 0.126±0.032%, 0.049±0.085%and 0.025±0.018% for APO targeted, CYTO targeted and ER targetedexpressions respectively (N=3). FIG. 8 summarizes this quantification ofexpressed U-ACTX-Hv1a (as % TSP values) for the various transformedtobacco leaves described above. These results indicated that APOtargeted transgene expression resulted in the greatest accumulation ofcorrectly folded ICK motif protein expressed in the leaves.

Overall, although the tobacco leaves transformed to produce CYTOtargeted, transgenic GFP fused U-ACTX-Hv1a presented the most potentgreen fluorescence signal, iELISA results detected the least U-ACTX-Hv1apeptide in these transgenic tobacoo leaves, in fact, considerably lessthan what was detected for leaves transformed for ER targeted expression(which had weakest green fluorescence signal). In iELISA assays, theprimary antibody (rabbit anti-U-ACTX-Hv1a antibody) can only bind on thecorrectly folded U-ACTX-Hv1a peptide.

Example 3 Alternate Signal Peptides for Expression of ICK Motif Proteinsin Plants

Since ER signal peptide may play a role in the protein expression level,two other ERSPs were tested using the FECT expression system describedin the prior examples. The two ERSP candidates were tobacco extensinsignal peptide, abbreviated as “E” in this study (Memelink et al, thePlant Journal, 1993, V4: 1011-1022.), and one of its variantsabbreviated as “E*” (Pogue G P et al, Plant Biotechnology Journal, 2010,V8: 638-654.). Their amino acid sequences are listed below (N′ to C′,one letter code, with non-identical residues in bold font):

Then, in order to add a Pac I restriction site atits 5′ terminus and add part of 5′ terminal DNA sequence of GFP at its3′ terminus, a further PCR was performed using the E DNA sequence as atemplate, yielding a 117 bp DNA fragment. This fragment was then used asthe forward PCR primer to amplify the DNA sequence encoding the GFP-IGERlinker-U-ACTX-Hv1a ORF from the vector pFECT-BGIH (refer to Example 1and Example 2), thus producing a U-ACTX-Hv1a expression ORF encoding(from N′ to C′ terminus) extensin signal peptide-GFP-IGERlinker-U-ACTX-Hv1a, following one of our ICK motif protein expressionORF design as ERSP-Sta-L-ICK. This expression ORF, named “EGIH”, has aPac I restriction site at its 5′ terminus and Avr II restriction site atthe 3′ terminus. EGIH has the following DNA sequence:

Three different FECT expression vectors, pFECT-BGIH, pFECT-EGIH andpFECT-E*GIH, were used to transiently express GFP fused U-ACTX-Hv1aprotein in tobacco plants to evaluate how the protein expression levelis affected by the different ERSPs. The three FECT expression vectorswere transformed into Agrobacterium, GV3101, and then the transformedGV3101 was injected into tobacco leaves for transient expression of GFPfused U-ACTX-Hv1a protein in tobacco leaves using the techniquesdescribed in Example 1.

The expression levels of GFP fused U-ACTX-Hv1a from three different FECTexpression vectors described above are first evaluated visually bydetecting green fluorescence under UV light. Green fluorescence from thetransiently transformed tobacco leaves from the three different FECTvectors is visible to the naked eye. All of the leaves showed similarlevels of green fluorescence, suggesting that none of the three ERSPstested contributed to a significant increase in the expression level ofGFP fused U-ACTX-Hv1a protein.

Total soluble protein samples were extracted from the tobacco leavestransformed with the three ERSP FECT vectors as described above(protocol is described in detail in Example 1). Pierce Coomassie Plusprotein assay was then performed (as described in Example 1) todetermine the concentration of the total soluble protein in theresulting TSP samples, yielding values of 0.85±0.68 μg/μL, 0.70±0.47μg/μL and 0.76±0.77 μg/μL for samples corresponding to the BGIH, EGIHand E*GIH expression ORFs respectively (N=4).

Indirect ELISA was then performed using the TSP extracts (as describedin Example 1) to quantify the expression level of the U-ACTX-Hv1aprotein as a percentage of the total soluble protein (% TSP), yieldingvalues of 0.39±0.17% (N=3, as one data point was taken out as outliner),0.48±0.26% (N=4), and 0.62±0.38% (N=4) for samples corresponding to theFECT vectors with BGIH, EGIH and E*GIH expression ORFs respectively.FIG. 9 summarizes the estimated U-ACTX-Hv1a levels as percentage in thetotal soluble protein (% TSP) for all of the samples taken from thetobacco leaves transformed with the three ERSP ORF described above.Although the data of % TSP from three FECT vector transformation lookeddifferent, they are not statistically different by Student's t-test. Inother words, the three ERSPs did not make difference in the expressionlevel of U-ACTX-Hv1a in the transiently transformed tobacco leaves.

Example 4 Stabilizing Protein Expressed as Fusion Protein to the ICKMotif Protein Helps the Accumulation of ICK Motif Protein in TransformedPlants

The ICK motif protein for plant expression in this example wasomega-ACTX-Hv1a, originating from the Australian Blue Mountains FunnelWeb Spider, Hadronyche versuta. Omega-ACTX-Hv1a has the following aminoacid sequence (one letter code):

(SEQ ID NO: 24) SPTCIPSGQPCPYNENCCSQSCTFKENENGNTVKRCD

The FECT expression system was used to express omega-ACTX-Hv1a in thetobacco plant, Nicotiana benthamiana. Two FECT vectors encodingdifferent omega-ACTX-Hv1a expression ORFs were engineered. One of theseexpression ORFs encoded omega-ACTX-Hv1a with Barley Alpha-Amylase Signalpeptide (BAAS) at its N′ terminus without any stabilizing protein. Thisexpression ORF, referred to herein as “BO”, was subcloned to yield theFECT expression vector pFECT-BO. The other omega-ACTX-Hv1a expressionORF encodes a translational fusion of omega-ACTX-Hv1a to the protein Juna 3 The mature Jun a 3 is a ˜30 kDa plant defending protein which isalso an allergen for some people, is produced by Juniperus ashei treesand is used in this ORF as a translational stabilizing protein (STA.)Its amino acid sequence is listed below (one letter code):

ID.27The IGER linker, encoded by the sequence between the omega-ACTX-Hv1adomain and Jun a 3 domains that are encoded in the ORF, is described indetail in Example 1. Taken together, this omega-ACTX-Hv1a expression ORFis referred to as S-Juna3-IGER-Omega, or SJIO. Likewise, the FECT vectorinto which the SJIO expression ORF was inserted was named pFECT-SJIO.

The two omega-ACTX-Hv1a FECT expression vectors, pFECT-BO andpFECT-SJIO, were used to transiently express omega-ACTX-Hv1a protein intobacco plants. The two FECT expression vectors were transformed intoAgrobacterium strain GV3101, and the resulting GV3101 transformant wasinjected into tobacco leaves for transient expression of omega-ACTX-Hv1ain tobacco leaves using the techniques described in detail in Example 1.

At day 6 post-tobacco transformation, transformed tobacco leaves werecollected and total soluble leaf proteins were extracted from the leaves(refer to Example 1 for detailed methods). Pierce Coomassie Plus proteinassay was then performed to determine the concentrations of the totalsoluble leaf protein, yielding values of 3.047±0.176 μg/μL (N=2) and2.473±0.209 μg/μL (N=2) for the leaves transformed with constructsencoding pFECT-SJIO and pFECT-BO respectively.

The indirect ELISA protocol was then performed using the TSP extractsabove as described in Example 1 to quantitatively evaluate theexpression level of the omega-ACTX-Hv1a protein as percentage of thetotal soluble protein (% TSP), yielding values of 0.133±0.014% (N=2) and0.0004±0.0003% (N=2) for the leaves transformed with the pFECT-SJIO andpFECT-BO vectors respectively. These data indicated that omega-ACTX-Hv1aexpressed as a translational fusion to Jun a 3 accumulated to a morethan 300-fold higher steady state level than that of omega-ACTX-Hv1aexpressed without translational fusion to the Jun a 3 protein.

Example 5 A Cleavable Linker Between the Stabilizing Protein Domain andthe ICK Motif Protein Domains in an ICK Motif Fusion Protein ExpressionORF Enhances the Insecticidal Activity of the Resulting ICK MotifProtein Expressed in a Transgenic Plant

Since most chewing insects secret trypsin into their guts to digestfood, we designed a fusion protein expression ORF that encoded a trypsincleavable linker between the stabilizing protein domain and the ICKmotif protein domain of the fusion, in order to facilitate release ofthe ICK motif domain from the intact fusion protein in the insect gut.

The ICK motif protein for plant expression here was omega-ACTX-Hv1a,whose amino acid sequence is as follows (one letter code):

(SEQ ID NO: 24) SPTCIPSGQPCPYNENCCSQSCTFKENENGNTVKRCD

The omega-ACTX-Hv1a expression ORF that was used encodes a fusionprotein comprising the following domains (N′ to C′): Jun a 3 signalpeptide::Jun a 3::IGER linker::omega-ACTX-Hv1a, as in the structuralformula ERSP-Sta-L-ICK described above. The origin and sequenc of Jun a3 is as described above in Example 4.

The ERSP used here was the Jun a 3 native signal peptide, as describedabove in Example 4.

The IGER linker, encoded by the sequence between the omega-ACTX-Hv1adomain and Jun a 3 domains that are encoded in the ORF, is described indetail in Example 1. Taken together, this omega-ACTX-Hv1a expression ORFis referred to as S-Juna3-IGER-Omega, or SJIO. Likewise, the FECT vectorinto which the SJIO expression ORF was inserted was named pFECT-SJIO.

The vector, pFECT-SJIO, was then used to transiently expressomega-ACTX-Hv1a protein in tobacco plants. The vector was transformedinto Agrobacterium, GV3101, and then the transformed GV3101 was injectedinto tobacco leaves for transient expression of omega-ACTX-Hv1a in theleaves using the techniques described in detail in Example 1.

On day 6 post tobacco leaf transformation, 3.3 g of transformed tobaccoleaf was collected and ground in liquid nitrogen. 50 mL of TSP-Selbuffer was used to extract the total soluble proteins (TSP) from theground leaves by following the procedure described in Example 1. A totalof 26 mL extract was recovered from the TSP extraction procedure, whichwas then evenly split into two samples, A and B, with 13 mL extract foreach group. Sample A was treated with trypsin to release omega-ACTX-Hv1afrom the fused Jun a 3 protein by adding 1.3 mL of 1 mg/mL trypsin in 1mM HCl at 37° C. for 1 hour. Sample B was not treated by trypsincleavage. To get omega-ACTX-Hv1a in the concentration range ofbioactivity, both groups were concentrated in the same way as following.First, the extractions were loaded into a concentrator with 10 kD cutofffilter membrane and spun at 3200 g for 2 hours. Then 1.4 mL retentatefrom Sample A and 1.1 mL retentate from Sample B were saved for latertests. The 12.5 mL filtrate from Sample A and 12.5 mL filtrate fromSample B were futher concentrated by being spun in concentrators with 1kD cutoff filter membranes at 3200 g for 16 hours. 1.3 mL retentate wasrecovered from Sample A and 1.1 mL retentate was recovered from SampleB. Both 1 kD cutoff filtration retentates were saved for later tests.This sample concentration procedure was summarized in FIG. 10. The totalTSP extraction from pFECT-SJIO transformed tobacco leaves was splitevenly to two samples. One sample (A) was treated by trypsin cleavageand the other (B) was not. Both groups were concentrated by being spunin the concentrators with 10 kD and then I kD cutoff filter membranes,and the retentates from the 10 kD and 1 kD cutoff filtration were savedfor further tests.

The SJIO expression ORF expressed a fusion protein as following, Jun a3::IGER::Omega-ACTX-Hv1a, which comprises a total of 266 amino acidresidues and has a predicted molecular weight of 28,204.28 Da. Thetrypsin cleavage of this fusion protein should release anomega-ACTX-Hv1a with molecular weight of 4049.2 Da and Jun a 3::IGERfusion protein with molecular weight of 24,155.1 Da. Therefore, if thetrypsin cleavage reaction is complete in the treatment, then theanticipated major components of the filtration samples are as follows:

Sample A 10 kD filtration retentate: Jun a 3::IGER fusion.Sample A 1 kD filtration retentate: Omega-ACTX-Hv1a.Sample B 10 kD filtration retentate: Jun a 3::IGER::Omega-ACTX-Hv1afusion.

Sample B 1 kD filtration retentate: no SRO expressed protein.

To quantify the omega-ACTX-Hv1a peptide in the retentate samples, iELISAwas performed as described in Example 1. The detected omega-ACTX-Hv1aconcentrations in the samples were as follows:

Sample A 10 kD filtration retentate: 1.328 ng/μL of omega-ACTX-Hv1a,total 1.86 μg.Sample A 1 kD filtration retentate: 2.768 ng/μL of omega-ACTX-Hv1a,total 3.60 μg.Sample B 10 kD filtration retentate: 12.656 ng/μL of omega-ACTX-Hv1a,total 13.92 μg.Sample B 1 kD filtration retentate: 0.752 ng/μL of omega-ACTX-Hv1a,total 0.83 μg. As indicated, Omega-ACTX-Hv1a was detected in allfiltration samples that were analyzed. The detected omega-ACTX-Hv1a inthe Group A 10 kD filtration retentate is presumably due in large partto physical retention of the uncleaved fusion protein. Likewise theomega-ACTX-Hv1a detected in the Group B 1 kD filtration retentate samplecould be due to a low rate of spurious filtration of the uncleavedfusion protein through the 10 kD cutoff filter membrane.

To confirm the trypsin-cleavage reaction was successful, reverse phaseHigh Performance Liquid Chromatography (rpHPLC) was performed to analyzethe components in the reserved filtration samples. HPLC was performedusing a Varian E218 HPLC system with an Onyx 100 monolithic C₁₈ column(4.6×100 mm), using water with 0.1% trifluoroacetic acid (solvent A) andacetonitrile with 0.1% trifluoroacetic acid (solvent B) as mobile phasecomponents. The omega-ACTX-Hv1a peptide was eluted from the column at aflow rate of 2 mL per minute using a linear gradient of 10-20% solvent Bover 10 minutes. Samples of 99% pure synthetic omega-ACTX-Hv1a were usedin rpHPLC to produce a standard curve (relating peak area to mass ofpeptide injected). FIG. 11 shows three separate elution profiles, 11A,11B, 11C. As shown in FIG. 11A, the omega-ACTX-Hv1a peptide eluted at6.5 minutes post-injection. When a 500 μL sample from Group B 1 kDfiltration retentate was loaded into the HPLC system, there was noprotein peak between 6 and 7 minutes post-injection in the correspondingHPLC chromatograph (FIG. 11B). When a 500 μL sample from Group A 1 kDfiltration retentate was loaded into the HPLC system, there was a peakat retention time of 6.3 minute (see dotted line in FIG. 11) in thecorresponding chromatograph, representing omega-ACTX-Hv1a released fromthe fusion protein by trypsin cleavage (FIG. 11C). The area of this peakcorresponded to a concentration of omega-ACTX-Hv1a of between 16-70ng/μL in the Sample A 1 kD filtration retentate (depending on theapproach used to integrate the peak).

The reserved filtration samples were used to perform housefly injectionbioassays to test the activity of the omega-ACTX-Hv1a in the fusionprotein form and in the released form from the fusion protein. Houseflypupae (Musca domestica) were purchased from Benzon Research, Inc. andkept at 25° C. in a plastic box with air holes on the box lid and flyfood (1:1 ratio sugar and powder milk) and cotton balls soaked in waterin the box. On the day after adult housefly emergence, the flies wereimmobilized using a CO₂ line and then kept immobile using a CO₂ infusionpad. Flies weighing 12-18 mg were selected for the injection bioassay.To perform housefly injection, a microapplicator loaded with a 1 ccglass syringe with a 30 gauge needle, in which the injection solutionwas loaded, was used to deliver 0.5 μL doses into the dorsal thorax ofthe flies. The injected flies were then put into labeled boxes with airholes, and mortality was scored 24 hours post-injection. The followingsamples were injected into houseflies (groups of 10 flies were used foreach sample):

Water injection as negative control.Group A 10 kD filtration retentate.Group A 1 kD filtration retentate.Group B 10 kD filtration retentate.Group B 1 kD filtration retentate.0.13 mg/mL trypsin solution as negative control.At 24 hrs. post injection, the Sample A 10 kD filtration retentate andSample A 1 kD filtration retentate caused 100% housefly mortality, while0% mortality was observed for the flies injected with the other samples.Pure, native sequence omega-ACTX-Hv1a showed an LD₅₀ of 100 pmol/gram ofhousefly in this housefly injection bioassay; hence, to generate 100%mortality in this paradigm, the concentration of the injectedomega-ACTX-Hv1a must at least 25 ng/μL. This is consistent with thebioassay results, since HPLC analysis of the Sample A 1 kD filtrationretentate indicated a concentration of concentration of omega-ACTX-Hv1aof 16-70 ng/μL. Filtration samples that did not comprise material thatwas treated with trypsin cleavage did not generate mortality in thehousefly injection bioassay, indicating that the Jun a 3 fusedomega-ACTX-Hv1a was considerably less active than native-sequenceomega-ACTX-Hv1a cleaved away from the fusion construct by trypsin.Therefore, the linker region of a plant ICK motif protein expression ORFcan show enhanced insecticidal function when designed to be cleavable,such that the ICK motif domain of the ICK fusion protein can be releasedfrom the other structural domains of the protein by proteolysis.

Part II. High Production Peptides

The ability to successfully produce insecticidal peptides on acommercial scale, with reproducible peptide formation and folding, andwith cost controls can be challenging. The wide variety, uniqueproperties and special nature of peptides, combined with the hugevariety of possible productions techniques can present an overwhelmingnumber of approaches to peptide production.

There are few if any descriptions, however, that describe how to changea peptide so that it will be produced in a biological system at a muchhigher rate of production than the peptide is typically produced beforeit is changed. Here we present a way to change the composition of apeptide and in so doing increase the rate and amount and simultaneouslylower the cost of peptide production. We describe novel ways of changingor “converting” one peptide into a different, more cost effectivepeptide, yet one which surprisingly is just as toxic as before it wasconverted.

We describe examples of these novel converted peptides, and we show howthese methods for altering or converting a peptide can make asignificant improvement in the yield of peptides without makingsignificant changes in its activity. The new processes, new peptides,new formulations, and new organisms for producing those peptides aredescribed and claimed herein. A process is described which increases theinsecticidal peptide production yield from yeast expression systems byadding a dipeptide at the N terminus of insecticidal peptides. Theaddition of a dipeptide does not adversely affect the insecticidalactivities of insecticidal peptides.

We describe examples of these novel converted peptides, and we show howthese methods for altering or converting a peptide can make asignificant improvement in the yield of peptides without makingsignificant changes in its activity. The new processes, new peptides,new formulations, and new organisms for producing those peptides aredescribed and claimed herein.

Detailed procedures for making high production peptides.

We describe a process and peptide that can increase peptide production.When followed these techniques will provide a coverted peptide by addinga dipeptide at the N-terminus of the native peptide that has betterproduction rate than the native peptide in three different ways. First,the over-all average yield of the dipeptide-native peptide strains isbetter than that of the native strains; second, the median yield of thedipeptide-native peptide strains is better than that of the native; andthird, there are more dipeptide strains at the higher yield range thanthere are for native peptide strains. The process described here can beused in various in vivo systems, including plants, animals and microbes.The invention requires the addition of a dipeptide to the N-terminus ofthe native peptide, which is the peptide that was known before thedipeptide is added. The known peptide is then “converted”, and it canthen be made with greater yields than were previously thought possible.In one embodiment insecticidal peptides are linked to a dipeptide. Thesedipeptide-native peptide systems can be used in plants that can producethe peptides. Plant produced peptides have a variety of uses fromproduction to simply making a toxic peptide available for consumption bya damaging insect, thus either protecting the plants or possiblyproviding other benefits.

In one embodiment we describe a process for increasing insecticidalpeptide production yield in yeast expression systems by the addition ofany dipeptide to the N-terminus of the insecticidal peptide. Thedipeptide is composed of a non-polar amino acid and a polar amino acid.The non-polar amino acid may be selected from glycine, alanine, proline,valine, leucine, isoleucine, phenylalanine and methionine. Glycine isthe preferred non-polar amino acid. The polar amino acid may be selectedfrom serine, threonine, cysteine, asparagine, glutamine, histidine,tryptophan and tyrosine. Serine is the preferred polar amino acid. Theprocess and amino acids are described where the non-polar amino acid isat the N-terminus of the dipeptide and in one embodiment the preferredN-terminus of the dipeptide is glycine. The process and amino acids aredescribed where the polar amino acid is at the C-terminus of thedipeptide and in one embodiment the preferred C-terminus of thedipeptide is serine.

In one embodiment of the invention the dipeptide is glycine-serine,gly-ser or GS. These amino acids are typically encoded by the followingcodons: Gly may be encoded by codons such as GGT, GGC, GGA, GGG and Sermay be encoded by codons such as TCT, TCC, TCA, TCG, AGT, and AGC.

The transgenes of the insecticidal peptides are designed such that theirtransgene sequences are optimized for the specific expression that maybe needed. For example, the transgenes of insecticidal peptides may beoptimized for expression in yeast, plants, bacteria, and viruses.Examples of such uses of the invention would include the engineering andoptimization of transgenes for crops like maize and soybean, with thepurpose of protecting them from insect pests. In one example we designtransgenes of insecticidal peptides such that their transgene sequencesare optimized for the specific expression in yeast expression systems,using for example, Kluyveromyces lactis, Pichia pastoris, andSaccharomyces cerevisiae. Other suitable yeast expression systems areknown in the art. The nucleotide codons for a dipeptide, such asglycine-serine, (gly-ser) are added to the 5′ end of the transgenesequences of the mature insecticidal peptides. The transgene sequencesare then ligated into appropriate expression vectors, which can provideappropriate selection markers, strong promoter-terminator sets for thespecific yeast expression system, signal sequences for secretion, andcleavage sites between the respective signal sequences and maturepeptide sequences. The insecticidal peptide expression vectors are thentransformed into yeast cells, by means known to one skilled in the art,including either electroporation or chemical transformation methods, inorder to generate stable peptide expression yeast strains. When theseyeast strains grow in appropriate media, they produce insecticidalpeptides modified by the addition of a dipeptide sequence,glycine-serine, to the N-terminus of the mature insecticidal peptides,which are secreted into the growth media. The addition of the dipeptide,glycine-serine, to the N-terminus of the mature insecticidal peptides,significantly improves the yield of the insecticidal peptides withoutadverse effects on the insecticidal activities of the peptides.

Our data shows that any Cysteine Rich Insecticial Peptide (CRIP) can bemade to grow at significantly higher yields than would otherwise bepossible using the procedures we describe here. We have demonstrated theboth ICK and non ICK types of CRIPs can have their yields dramaticallyimproved using the High Production techniques we described. Here weprovide evidence of dramatic and surprising increases in yields of twovery diverse types of CRIPS.

The insecticidal peptides that can be converted may be selected frominsecticidal venom, for example the venom of a spider. The spider may bean Australian funnel web spider. The peptides from the genus of Atrax orHadronyche are U-ACTX-Hv1a and its analogs and are easily made specialusing the procedures described herein. Specific peptide examples fromspiders are described in the sequence listing provided herein. Thesepeptides and others can be converted using the procedures describedherein.

The insecticidal peptides that can be converted may be selected from seaanemone toxins such as from Anemone viridis as described in Example 3.Sea anemones are far removed in their normal habitat from the funnel webspiders of the genus of Atrax or Hadronyche and the venom from Anemoneviridis is not considered a ICK type of venom, as is venomous peptidesfrom Atrax or Hadronyche but in spite of that the venom of the seaurchin, like the U-ACTX-Hv1a toxic peptides and other insecticidalvenoms is that they are all a type of venom that we call Cysteine RichInsecticidal Peptide or CRIP and identified here for the first time assuch. The procedures described herein, in all the sections, are expectedand believed to work with all of the peptide in the sequence listingsand all of the peptides related to those sequences that would beunderstood by one skilled in the art to be a Cysteine Rich InsecticidalPeptide or CRIP. All such peptides and others can be converted using theprocedures described herein.

In addition to the process, we also disclose novel High ProductionPeptides, herein “HP peptides,” comprising a dipeptide bound to one endof a peptide. In our embodiments the peptide is an insecticidal peptide.In one embodiment the dipeptide is added to the N-terminus of thepeptide. We have demonstrated success in producing high yield strainswith both ICK and non-ICK CRIP peptides. In a further embodiment thedipeptide is composed of a non-polar amino acid and a polar amino acid.In a further embodiment the non-polar amino acid is selected fromglycine, alanine, proline, valine, leucine, isoleucine, phenylalanineand methionine, and the polar amino acid is selected from serine,threonine, cysteine, asparagine, glutamine histidine, tryptophan andtyrosine. In one specific embodiment an HP peptide is comprised of apeptide which is modified to have the dipeptide of glycine-serine as thefirst two amino acids of an otherwise unmodified, mature peptide. HPpeptides may be produced by adding glycine-serine to the U peptide andits analogs to create HP peptides.

The modified peptides made by the processes described herein are new andare separately claimed. These peptides are described by all of theirproperties and not simply their sequence. These peptides are novel andhave unique properties. Both HP peptides and the process of making themare disclosed and claimed herein.

Examples of useful peptides are well known and can be found in numerousreferences. One class of useful peptides is insecticidal peptides.Insecticidal peptides can be identified by their peptide nature andtheir activity, usually oral or injection insecticidal activity. Here weprovide a few examples to better illustrate and describe the invention,but the invention is not limited to these examples. All of theseexamples and others not shown here are descriptive of new materials,described and claimed here for the first time.

HP (High Production) peptides are defined here as any peptides capableof being produced at greater than normal rates of production using thetechniques described herein. Such peptides may have insecticidalactivity. Typically, insecticidal peptides show activity when injectedinto insects but most do not have significant activity when applied toan insect topically. The insecticidal activity of HP peptides ismeasured in a variety of ways. Common methods of measurement are widelyknown to those skilled in the art. Such methods include, but are notlimited to determination of median response doses (e.g., LD₅₀, PD₅₀,LC₅₀, ED₅₀) by fitting of dose-response plots based on scoring variousparameters such as: paralysis, mortality, failure to gain weight, etc.Measurements can be made for cohorts of insects exposed to various dosesof the insecticidal formulation in question. Analysis of the data can bemade by creating curves defined by profit analysis and/or the HillEquation, etc. In such cases, doses would be administered by hypodermicinjection, by hyperbaric infusion, by presentation of the insecticidalformulation as part of a sample of food or bait, etc.

Specific examples of HP peptides disclosed for purposes of providingexamples and not intended to be limiting in any way, are the U peptideand its homologies, which origin from the venoms of AustralianFunnel-web spiders. The description of these peptides can be found inthis document in earlier sections.

The Examples in this specification are not intended to, and should notbe used to limit the invention, they are provided only to illustrate theinvention.

As noted above, many peptides are suitable candidates as the subject ofthe process to make special. The sequences noted above, below and in thesequence listing are especially suitable peptides that can be madespecial, and some of these have been made special according to thisinvention with the results shown in the examples below.

SEQ ID NO: 29 (one letter code). Named “Av3+2,” It has disulfide bridgesat positions: 5-19, 6-13, 8-24. The molecular weight is 3076.47 Daltons.

Preparation of the HP Peptides

The HP peptides described herein can be prepared as below. The openreading frames (ORFs) of the insecticidal peptides are designed suchthat their nucleotide sequences are optimized for species-specificexpression. Shown below is a specific example of a process forincreasing insecticidal peptide production yield from yeast expressionsystems by addition of a dipeptide to the N-terminus of the insecticidalpeptide. The dipeptide is composed of a non-polar amino acid and a polaramino acid. The non-polar amino acid may be selected from glycine,alanine, proline, valine, leucine, isoleucine, phenylalanine andmethionine and glycine is the preferred non-polar amino acid. The polaramino acid may be selected from serine, threonine, cysteine, histidine,tryptophan, tyrosine, asparagine and glutamine and serine is thepreferred polar amino acid. In the example below, the non-polar aminoacid is at the N-terminus of the dipeptide and it is glycine. In theexample below, the polar amino acid is at the C-terminus of thedipeptide and it is serine.

The insecticidal peptide ORF is designed for secretion from host yeastcells as follows: the ORF starts with a signal peptide sequence,followed by DNA sequence encoding a Kex 2 cleavage site(Lysine-Arginine), followed by the insecticidal peptide transgene withaddition of glycine-serine codons at the 5′ terminus, and finally endswith a stop codon at the 3′ terminus. All these elements will beexpressed to a fusion peptide in yeast cells as a single open readingframe. An α-mating factor signal sequence is most frequently used tofacilitate metabolic processing of the recombinant insecticidal peptidesthrough the endogenous secretion pathway of the recombinant yeast, i.e.the expressed fusion peptide will typically enter the EndoplasmicReticulum, wherein the α-mating factor signal sequence is removed bysignal peptidase activity, and then the resulting pro-insecticidalpeptide will be trafficked to the Golgi Apparatus, in which theLysine-Arginine dipeptide mentioned above is completely removed by Kex 2endoprotease, after which the mature, HP insecticidal peptide,comprising the additional non-native glycine-serine dipeptide at itsN-terminus, is secreted out of the cells.

To enhance insecticidal peptide expression level in the recombinantyeast cells, the codons of the insecticidal peptide ORF are usuallyoptimized for expression in the specific host yeast species. Naturallyoccurring frequencies of codons observed in endogenous open readingframes of a given host organism are not necessarily optimized for highefficiency expression. Furthermore, different yeast species (forexample, Kluyveromyces lactis, Pichia pastoris, Saccharomycescerevisiae, etc.) have different optimal codons for high efficiencyexpression. Hence, codon optimization should be considered for thepeptide ORF, including the sequence elements encoding the signalsequence, the Kex2 cleavage site and the insecticidal peptides, sincethey are initially translated as one fusion peptide in the recombinantyeast cells.

The codon-optimized peptide expression DNAs are then ligated intoappropriate expression vectors for yeast expression. There are manyexpression vectors available for yeast expression, including episomalvectors and integrative vectors, and they are usually designed forspecific yeast strains. One should carefully choose the appropriateexpression vector in view of the specific yeast expression system whichwill be used for the peptide production. Here we used integrativevectors, which will integrate into chromosomes of the transformed yeastcells and be stable through cycles of cell division and proliferation.

The expression vectors usually contain some E. coli elements for DNApreparation in E. coli, for example, E. coli replication origin,antibiotic selection marker, etc. The vectors also contain an array ofthe sequence elements needed for expression of the transgene ofinterest, for example, transcriptional promoters, terminators, yeastselection markers, integrative DNA sequences homologous to host yeastDNA, etc. There are many suitable yeast promoters available, includingnatural and engineered promoters. In our efforts, yeast promoters suchas pLAC4, pAOX1, pUPP, pADH1, pTEF, pGal1, etc. have been used. We alsoused the following commonly used yeast selection markers: acetamideprototrophy selection, zeocin-resistance selection, geneticin-resistanceselection, nourseothricin-resistance selection, uracil deficiencyselection. Other markers known to one skilled in the art could also beused. The integrative DNA sequences are homologous to targeted genomicDNA loci in the transformed yeast species, and such integrativesequences include pLAC4, 25S rDNA, pAOX1, and TRP2, etc. The locationsof insecticidal peptide transgenes can be adjacent to the integrativeDNA sequence (Insertion vectors) or within the integrative DNA sequence(replacement vectors).

To get more copies of insecticidal peptide ORF integrated into the hostyeast chromosomes, the expression vectors can be designed and generatedto contain two or three copies of insecticidal peptide expressioncassette. Each copy of the insecticidal peptide expression cassette inthe expression vector should contain independent and complete expressionstructures including promoter, signal sequence, Kex2 cleavage sequenceand, the insecticidal peptide transgene, stop codon transcriptionterminator.

The peptide expression vectors are then transformed into yeast cells.First, the expression vectors are usually linearized by specificrestriction enzyme cleavage to facilitate chromosomal integration viahomologous recombination. The linear expression vector is thentransformed into yeast cells by a chemical or electroporation method oftransformation and integrated into the targeted locus of the yeastgenome by homologous recombination. The integration can happen at thesame choromosomal locus multiple times; therefore the genome of atransformed yeast cell can contain multiple copies of insecticidalpeptide transgenes. The successful transformants can be identified usinggrowth conditions that favor a selective marker engineered into theexpression vector and co-integrated into yeast chromosomes with theinsecticidal peptide transgenes; examples of such markers include, butaren't limited to, acetamide prototrophy, zeocin resistance, geneticinresistance, nourseothricin resistance, and uracil prototrophy.

Due to the influence of unpredictable and variable factors—such asepigenetic modification of genes and networks of genes, and variation inthe number of integration events that occur in individual cells in apopulation undergoing a transformation procedure—individual yeasttransformants of a given transformation process will differ in theircapacities to produce a transgenic insecticidal peptide. Therefore,yeast transformants carrying the insecticidal peptide transgenes shouldbe screened for high yield strains. Two effective methods for suchscreening, each dependent on growth of small-scale cultures of thetransformants to provide conditioned media samples for subsequentanalysis, use reverse-phase HPLC or housefly injection procedures toanalyze conditioned media samples from the transformants.

The transformant cultures are usually performed in 14 mL round bottompolypropylene culture tubes with 5-10 mL defined medium added to eachtube, or in 48-well deep well culture plates with 1-2 mL defined mediumadded to each well. The Defined medium, not containing crudeproteinaceous extracts or by-products such as yeast extract or peptone,is used for the cultures to reduce the protein background in theconditioned media harvested for the later screening steps. The culturesare performed at the optimal temperature, for example, 23.5° C. for K.lactis, for 5-6 days, until the maximum cell density is reached. Theinsecticidal peptides are now produced from the transformants andsecreted out of cells to the growth medium. To prepare samples for thescreening, cells are removed from the cultures by centrifugation and thesupernatants are collected as the conditioned media, which are thencleaned by filtration through 0.22 μm filter membrane and then madeready for insecticidal peptide production strain screening, a couple ofexamples of such screening methods are described below.

One of the screening methods is reverse-phase HPLC (rpHPLC) screening oftransformants. In this screening method, an HPLC analytic column withbonded phase of C18 is used. Acetonitrile and water are used as mobilephase solvents, and a UV absorbance detector set at 220 nm is used forthe peptide detection. Appropriate amounts of the conditioned mediumsamples are loaded into the rpHPLC system and eluted with a lineargradient of mobile phase solvents. The corresponding peak area of theinsecticidal peptide in the HPLC chromatograph is used to quantify theinsecticidal peptide concentrations in the conditioned media. Knownamounts of pure insecticidal peptide are run through the same rpHPLCcolumn with the same HPLC protocol to confirm the retention time of thepeptide and to produce a standard peptide HPLC curve for thequantification.

A second screening method is the housefly injection assay. Insecticidalpeptide can kill houseflies when injected in measured doses through thebody wall of the dorsal thorax. The efficacy of the insecticidal peptidecan be defined by the median lethal dose of the peptide (LD50), whichcauses 50% mortality of the injected houseflies. The pure insecticidalpeptide is normally used in the housefly injection assay to generate astandard dose-response curve, from which an LD50 value can bedetermined. Using an LD50 value from the analysis of a standarddose-response curve of the pure insecticidal peptide in question,quantification of the insecticidal peptide produced by a yeasttransformant can be achieved using a housefly injection assay performedwith serial dilutions of the corresponding conditioned media.

The insecticidal peptide production strain screen can identify the highyield yeast strains from hundreds of transformants. These strains can befermented in bioreactor to achieve up to 6 g/L yield of the insecticidalpeptides when using optimized fermentation media and fermentationconditions. The higher rates of production can be anywhere from 20 to400, 20 to 100, 20 to 200, 20 to 300, 40 to 100, 40 to 200, 40 to 300,40 to 400, 60 to 100, 60 to 200, 60 to 300, 60 to 400, 80 to 100, 80 to200, 80 to 300, 80 to 400, 100 to 150, 100 to 200, 150 to 200, 200 to250, 250 to 300, 250 to 350, 250 to 400, 300 to 350, 300 to 400% and 350to 400 or any range of any value provided or even greater yields thancan be achieved with a peptide before conversion, using the same orsimilar production methods that were used to produce the peptide beforeconversion.

Any of the sequences from the sequence listing, and as far as we knowany CRIP could all be used to make high production peptides similar toeither the ACTX motifs from the Australian Blue Mountain Funnel-webSpider we call the “U+2” peptide described below, or the Av3+2 peptideof the toxic sea anemone, Anemone viridis, that we teach and describe inthe examples below by using procedures taught here and the knowledge ofone ordinarily skilled in the art. In addition, any other suitable CRIPpeptide could be used in a like manner to produce a high production orplus 2, i.e. +2 peptide.

Examples of High Production Peptides

The Examples in this specification are not intended to, and should notbe used to limit the invention, they are provided only to illustrate theinvention.

Example 1

Expression of native U and U+2-ACTX-Hv1a in Kluyveromyces lactis (K.lactis).

Insecticidal peptides to express:

U + 2-ACTX-Hv1a: (SEQ ID NO: 5)GSQYCVPVDQPCSLNTQPCCDDATCTQERNENGHTVYYCRA and Native U-ACTX-Hv1a:(SEQ ID NO: 6) QYCVPVDQPCSLNTQPCCDDATCTQERNENGHTVYYCRA

To express the two insecticidal peptides above in K. lactis, theexpression vector, pKLAC1, and the K. lactis strain, YCT306, were used,which are available from New England Biolabs, Ipswich, Mass., USA.pKLAC1 vector is an integrative expression vector. Once the U+2 andnative U-ACTX-Hv1a transgenes were cloned into pKLAC1 and transformedinto YCT306, their expression was controlled by the LAC4 promoter. Theresulting transformants produced pre-propeptides comprising an α-matingfactor signal peptide, a Kex2 cleavage site and mature insecticidalpeptides. The α-Mating factor signal peptide guides the pre-propeptidesto go through the endogenous secretion pathway and finally the matureinsecticidal peptides are released into the growth media.

Codon optimization for U+2-ACTX-Hv1a expression was performed in tworounds. In the first round, based on some common features of highexpression DNA sequences, 33 variants of the peptide ORF, expressing anα-Mating factor signal peptide, a Kex2 cleavage site and theU+2-ACTX-Hv1a peptide, were designed and their expression levels wereevaluated in the YCT306 strain of K. lactis, resulting in an initial K.lactis expression algorithm. In the 2^(nd) round of optimization, fivemore variant U+2-ACTX-Hv1a peptide ORFs were designed based on theinitial K. lactis expression algorithm to further fine-tuned the K.lactis expression algorithm, and identified the best ORF for theU+2-ACTX-Hv1a peptide expression in K. lactis. This DNA sequence has anopen reading frame encoding an α-mating factor signal peptide, a Kex2cleavage site and a U+2-ACTX-Hv1a peptide. The optimized DNA sequencewas cloned into the pKLAC1 vector using Hind III and Not I restrictionsites, resulting in the U+2-ACTX-Hv1a expression vector, pLB10V5.

To enable integration of more copies of the optimized U+2-ACTX-Hv1atransgene into the K. lactis genome during transformation, generation ofa U+2-ACTX-Hv1a expression vector containing two copies of U+2-ACTX-Hv1aexpression cassette was processed as follows: A 3,306 bp intactU+2-ACTX-Hv1a expression cassette DNA sequence was synthesized, whichcomprised an intact LAC4 promoter element, a codon-optimizedU+2-ACTX-Hv1a peptide ORF element and a pLAC4 terminator element. Thisintact expression cassette was then ligated into the pLB10V5 vectorbetween Sal I and Kpn I restriction sites, downstream of the pLAC4terminator of pLB10V5, resulting in the double transgene U+2-ACTX-Hv1aexpression vector, pLB10V5D.

To generate a native U-ACTX-Hv1a expression vector, the pLB10V5 vectorwas mutagenized by deleting the glycine-serine codons at the 5′-terminusof the U+2-ACTX-Hv1a transgene region, using a Stratagene site-directmutagenesis kit. This mutagenesis resulted in a new vector, pLB12,containing a single copy of the codon-optimized native U-ACTX-Hv1aexpression cassette. To generate a double transgene native U-ACTX-Hv1aexpression vector, a Stratagene site-direct mutagenesis kit was usedagain to remove the glycine-serine codons at the 5′-terminus of theU+2-ACTX-Hv1a transgene region in the 3,306 bp U+2-ACTX-Hv1a expressioncassette transgene synthesized previously, followed by ligation toinsert the mutagenized cassette into the pLB12 vector between Sal I andKpn I restriction sites, resulting in the plasmid, pLB12D, an expressionvector comprising two intact copies of the codon-optimized nativeU-ACTX-Hv1a expression cassette.

The double transgene vectors, pLB10V5D and pLB12D, were then linearizedusing Sac II restriction endonuclease and chemically transformed intoYCT306 strain of K. lactis, according to instructions provided with a K.lactis Protein Expression Kit. The resulting transformants grew on YCBagar plate supplemented with 5 mM acetamide, which only theacetamidase-expressing transformants could use efficiently as ametabolic source of nitrogen.

For insecticidal peptide yield evaluations, 316 colonies were pickedfrom the pLB10V5D transformants plates, and 40 colonies were picked fromthe pLB12D transformants plates. Inocula from the colonies were eachcultured in 6 mL of the defined K. lactis media with 2% pure glyceroladded as a carbon source. Cultures were incubated at 23.5° C., withshaking at 280 rpm, for six days, at which point cell densities in thecultures had reached their maximum levels as indicated by lightabsorbance at 600 nm (OD600). Cells were then removed from the culturesby centrifugation at 4,000 rpm for 10 minutes. The resultingsupernatants (conditioned media) were filtered through 0.2 μm membranesfor HPLC yield analysis.

For the peptide yield evaluation, the filtered conditioned media sampleswere analyzed on an Agilent 1100 HPLC system equipped with an Onyxmonolithic 4.5×100 mm, C18 reverse-phase analytical HPLC column and anauto-injector. HPLC grade water and acetonitrile, both containing 0.1%trifluoroacetic acid, constituted the two mobile phase solvents used forthe HPLC analyses. The peak areas of both the native U and U+2-ACTX-Hv1were measured using HPLC chromatographs and then used to calculate thepeptide concentration in the conditioned media, which were then furthernormalized to the corresponding final cell densities (as determined byOD600 measurements) as normalized peptide yield.

Housefly injection bioassay was used to evaluate the insecticidalactivity of the peptides. The conditioned media were serially diluted togenerate full dose-response curves from the housefly injection bioassay.Before injection, adult houseflies (Musca domestica) were immobilizedwith CO₂, and 12-18 mg houseflies were selected for injection. Amicroapplicator, loaded with a 1 cc syringe and 30-gauge needle, wasused to inject 0.5 μL per fly doses of serially diluted conditionedmedia samples into houseflies through the body wall of the dorsalthorax. The injected houseflies were placed into closed containers withmoist filter paper and breathing holes on the lids, and they wereexamined by mortality scoring at 24 hours post-injection.

Normalized yields were calculated. Peptide yield means the peptideconcentration in the conditioned media in units of mg/L. But peptideyields are not always sufficient to accurately compare the strainproduction rate. Individual strains may have different growth rates,hence when a culture is harvested, different cultures may vary in celldensity. A culture with a high cell density may produce a higherconcentration of the peptide in the media, even though the peptideproduction rate of the strain is lower than another strain which has ahigher production rate. So the term “normalized yield” is created bydividing the peptide yield with the cell density in the correspondingculture and this allows a better comparison of the peptide productionrate between strains. The cell density is represented by the lightabsorbance at 600 nm with a unit of “A” (Absorbance unit).

Table 1, FIG. 12 and FIG. 13 summarize the U+2- and native U-ACTX-Hv1anormalized peptide yield distributions from the K. lactis strains. Theoverall averaged U+2-ACTX-Hv1a normalized peptide yield from the K.lactis strains was 4.06±3.05 mg/L.A, which was statisticallysignificantly higher than the averaged native U-ACTX-Hv1a normalizedpeptide yield, 2.73±1.25 mg/L.A, by Student's t-test at 99% confidencelevel. The median normalized peptide yield of the U+2-ACTX-Hv1a K.lactis strains was 9.36 mg/L.A, which was almost three times higher thanthe median yield of native U-ACTX-Hv1a strains (3.35 mg/L.A). TheU+2-ACTX-Hv1a peptide expression strains had much higher ratios of thestrain counts at high yield level than the native U-ACTX-Hv1a strains.All of these results indicated that the addition of the glycine-serinedipeptide to the N-terminus of the U-ACTX-Hv1a peptide contributes tosignificant improvement of the predicted yield for yeast transformantsexpressing this peptide.

Table 1 shows a comparison of peptide yields from K. lactis strains.

FIG. 12 shows the histograms of the normalized peptide yielddistributions for the U+2 and native U strains. The X scale shows therange of the normalized peptide yield. The Y scale on the left shows thefrequency of the U+2 producing strains in the specific range of thenormalized yield, and the Y scale on the right shows the frequency ofthe native U producing strains in the specific range of the normalizedyield. The black bars represent the U+2 yield distribution and the greybars represent the native U yield distribution. For example, the firstblack bar tells that about 0.03 (3%) of the total U+2 producing strainshave normalized yields between 0 and 0.5 mg/L.A. The strain counts aredifferent between native and +2 strains because 316 strains for U+2 werescreened and 40 strains for the native peptide were screened.

FIG. 13 shows the distribution of the peptide yields from U+2 and nativeU-ACTX-Hv1a produced from the K. lactis strains. The U+2 data is shownin black and the native U data is in gray. The x-axis shows the yield inmilligrams per liter and the y-scale shows the fraction of total U+2 ornative U production from K. lactis strains. The yield from the U+2strains, and the number of U+2 strains available that can produce highyields is far higher for the U+2 strains as compared to the native Ustrains.

Ordinarily one might expect making changes to a peptide sequence thatdramatically improves its yield could affect its toxicity. Surprisinglythat is not what happens with the dipeptides of this disclosure. Ourdata indicates the addition of the dipeptide, and especially theglycine-serine dipeptide, to the N-terminus of the U-ACTX-Hv1a peptide,does not lower the effectiveness of the insecticidal activities of thepeptide. FIG. 14 shows two dose-response curves for housefly injectionbioassays performed with the native and U+2-ACTX-Hv1a conditioned mediumsamples. The U+2-ACTX-Hv1a has a median lethal dose (LD50) of 76.8pmol/g, which is consistent with the LD50 of native U-ACTX-Hv1a, 77.6pmol/g.

Example 2

Peptide yields of transformants of the yeast, Pichia pastoris (P.pastoris), expressing either U+2-ACTX-Hv1a or U-ACTX-Hv1a were studied.

Two P. pastoris vectors, pJUGαKR and pJUZαKR, were used for theU+2-ACTX-Hv1a or native U-ACTX-Hv1a peptide expression in P. pastoris.pJUGαKR and pJUZαKR are available from Biogrammatics, Carlsbad, Calif.,USA. Both vectors are integrative vectors and use the uracilphosphoribosyltransferase promoter (pUPP) to enhance the heterologoustransgene expression. The only difference between the vectors is thatpJUGαKR provides G418 resistance to the host yeast, while pJUZαKRprovides Zeocin resistance.

Pairs of complementary oligonucleotides, encoding the native U-ACTX-Hv1aand U+2-ACTX-Hv1a respectively, were designed and synthesized for subcloning into the two yeast expression vectors. Hybridization reactionswere performed by mixing the corresponding complementaryoligonucleotides to a final concentration of 20 μM in 30 mM NaCl, 10 mMTris-Cl (all final concentrations), pH 8, and then incubating at 95° C.for 20 min, followed by a 9 hour incubation starting at 92° C. andending at 17° C., with 3° C. drops in temperature every 20 min. Thehybridization reactions resulted in two DNA fragments encodingU+2-ACTX-Hv1a and native U-ACTX-Hv1a peptides respectively. The two P.pastoris vectors were digested with BsaI-HF restriction enzymes, and thedouble stranded products of the Uization reactions were then sub clonedinto the linearized P. pastoris vectors using standard procedures.Following verification of the sequences of the four sub clones, plasmidaliquots were transformed by electroporation into the P. pastorisstrain, Bg08. The resulting transformed yeast, selected based onresistance to Zeocin or G418 conferred by elements engineered intovectors pJUZαKR and pJUGαKR, respectively, were cultured and screened asdescribed below. Since no transformant strains had more than oneantibiotic resistance marker, and since transformation procedures wereperformed the same for yeast cells transformed with the U+2-ACTX-Hv1atransgene as for those transformed with the native U-ACTX-Hv1atransgene, it is reasonable to presume that the distributions oftransgene copy number were comparable for the two populations oftransformants being compared below.

Recipes for media and stocks used for the P. pastoris cultures aredescribed as follows:

48-well Deep-well plates, sealed after inoculation with sterile,air-permeable tape, were used to culture the insecticidal peptide P.pastoris transformants. Colonies on the P. pastoris transformant plateswere picked and inoculated the deep-well plates with 1 mL media perwell, which was composed of MSM+0.2% PTM1+biotin (500× diluted from 200ppm stock) +1% glycerol (pure). Inoculated plates were grown 5 days at23.5° C. with 220 rpm shaking in a refrigerated incubator-shaker. 100 μL5% glycerol were added to each well of the plates at 2, 3, and 4 dayspost inoculation. On day 5 post-inoculation, conditioned media washarvested by centrifugation at 3700 rpm for 15 minutes, followed byfiltration using filter plate with 0.22 μM membrane. Filtered mediastored at −20° C. for further analyses.

0.3 mL aliquots of conditioned P. pastoris media prepared as describedabove were analyzed using rpHPLC described in EXAMPLE 1 to determine theconcentrations of the native U-ACTX-Hv1a or U+2-ACTX-Hv1a peptidepresent in the media. Results of this analysis are summarized in Table2, FIG. 15 and FIG. 16. The average peptide yields with a common meanand standard deviation are 67.0±27.9 mg/L for the U+2-ACTX-Hv1a P.pastoris strains and 42.9±18.3 mg/L for the native U-ACTX-Hv1a strains.A student's t-test indicated that the probability of such differingdistributions of yields is far below 1%. The median yield from theU+2-ACTX-Hv1a strains was 79.0 mg/L, far higher than that from thenative U-ACTX-Hv1a strains (44.7 mg/L). It is observed that theU+2-ACTX-Hv1a strains had much higher ratios of the strain counts athigh peptide yield level than the native U-ACTX-Hv1a strains. All theseresults support the conclusion that the extra glycine-serine dipeptideat the N-terminus of the U+2-ACTX-Hv1a significantly improved thecapacity of yeast transformants to produce this peptide and secrete itinto conditioned media.

Table 2 shows a comparison of peptide yields from P. pastoris strains.

To express the two non-ICK CRIP peptides above in Kluyveromyces lactis,the pKLAC1 vector and the Kluyveromyces lactis strain, YCT306, were usedas in example 1.

The Av3 and Av3+2 peptide ORF, which encode α-MF::Kex2 cleavagesite::Av3 (or Av3+2), were codon-optimized using previously determinedK. lactis expression algorithm.

The optimized Av3+2 expression ORF sequence is follows:

This optimized DNA sequence was cloned into pKLAC1 vector using Hind IIIand Not I restriction sites, resulting in the native Av3 expressionvector, pLB103.

The expression vectors, pLB102 and pLB103, were then linearized usingSac II restriction endonuclease and transformed into YCT306 strain of K.lactis, using the electroporation transformation method. The resultingtransformants grew on YCB agar plate supplemented with 5 mM acetamide,which only the acetamidase-expressing transformants could useefficiently as a metabolic source of nitrogen.

For insecticidal peptide yield evaluations, 48 colonies of pLB102transformants and 48 colonies of pLB103 transformants were picked up andinoculated 2.2 mL of the defined K lactis media with 2% sorbitol addedas a carbon source in 48-well deep-well plates with 5 mL volume capacityeach well. Cultures were processed at 23.5° C., with shaking at 280 rpm,for six days, when cell densities in the cultures were determined bylight absorbance at 600 nm (OD600). Cells were then removed from thecultures by centrifugation at 4000 rpm for 10 minutes. The resultingsupernatants (conditioned media) were filtered through 0.2 μm membranesfor HPLC yield analysis.

For the peptide yield evaluation, the filtered conditioned media sampleswere analyzed on an Agilent 1100 HPLC system equipped with an Onyxmonolithic 4.5×100 mm, C18 reverse-phase analytical HPLC column and anauto-injector. HPLC grade water and acetonitrile, both containing 0.1%trifluoroacetic acid, constituted the two mobile phase solvents used forthe HPLC analyses. The native Av3 or Av3+2 peak areas in the resultingHPLC chromatographs were used as indication of the peptide concentrationin the conditioned media, which were then further normalized to thecorresponding final cell densities (as determined by OD600 measurements)as normalized peptide yield.

Table 3, FIG. 17 and FIG. 18 summarize the Av3+2 and native Av3normalized peptide yield distributions from the K. lactis strains. Thenormalized peptide yield is represented by the peptide UV peak area inthe HPLC chromatograph divided by the corresponding cell density(represented by the OD600) at the end of the cell culture. The overallaveraged normalized peptide yield from the Av3+2 strains was 117.5±50.1mAu·sec/A, which was statistically significantly higher than that ofnative Av3 which was 29.8±16.1 mAu·sec/A, by Student's t-test at 99%confidence level. The median normalized peptide yield of the Av3+2 K.lactis strains was 106.7 mAu·sec/A, which was more than three timeshigher than that of native Av3 strains (31.7 mAu·sec/A). The Av3+2expression strains had much higher ratios of the strain counts at highyield level than the native Av3 strains (table 3). And as shown in FIG.18, overall at the any percentile of peptide yield, Av3+2 strains hadhigher yield than native Av3 strains. All of these results indicatedthat the addition of the glycine-serine dipeptide to the N-terminus ofthe Av3 peptide contributes to significant improvement of the peptideyield from yeast transformants expressing this peptide.

PART 3. In this Part we Describe Combinations of “CRIPS” and “PFIPS.”

A large number of venom peptides have been characterized as“insecticidal.” However, despite numerous reports, few have found anyutility in the market as actual or effective insecticides. In fact, onlyω-ACTX-Hv1a has been reported to be toxic by oral administration to theAmerican lone star tick Amblyomma americanum. No other spider toxinshave been reported to possess oral activity even in the modified gut ofticks. There has been a report that the bioavailability of thesepeptides may be increased by coupling them to a carrier protein such assnowdrop lectin (Galanthus nivalis agglutinin, GNA). Mukherjee, A. K.:Sollod, B. L.; Wikel, S. K.; King, G. F. “Orally active acaricidalpeptide tosins from spider venom.” Toxicon 2006, 47, 182-187. Garliclectins are reported to increase the absorption of toxins across theinsect midgut Fitches, E et. al. Insect Sci., 2008, 15, 483-495,Fitches, E., et. al., Insect Biochem. Mol. Biol. 2008, 38, 905-915.Firches, E. et. al., J. Insect Physiol. 2004, 50, 61-71. For example,fusion of the insecticidal spider toxin U2-SGTX-Sf1a (SFI1) to GNAsignificantly increased its oral toxicity to the tomato moth Laconobiaoleracea Down, R. E. et. al., Pest Manag. Sci. 2006, 62, 77-85, as wellas the rice brown planthopper Nilaparvata lugens and the peach-potatoaphid Myzus persicae. Surprisingly, a thioredoxin-ω-HXTX-Hv1a fusionprotein was found to be insecticidal in Helicoverpa armigera andSpodoptera littoralis caterpillars by topical application Khan, S. A.Transgenic Res. 2006, 15, 349-357. (although the fusion protein wasapplied topically in a solution containing high levels of imidazole, acompound known to have contact insecticidal activity; Pence, R. J.California Agric. 1965, 13-15. These efforts and findings clearlyindicate the importance of developing means to enhance the oralbioavailability of venom toxins. We think these efforts are alsomisdirected. In this disclosure we teach that fusion of insecticidalpeptides to carrier proteins that bind to the gut of insects isunnecessary. We describe a better way to deliver the “toxin” ininsecticidal peptides to insects. Without wishing to be bound by theory,it is our theory that PFIPS, or Pore Forming Insecticidal Proteins, actby selectively binding to receptors in the insect gut. The PFIPS then,in subsequent events, act to disrupt the membrane potential of theepithelial cells lining the gut. When an appropriate CRIP or TMOF isalso timely introduced to the gut at the same time the PFIPS are actingon the insect gut, the result is apotosis and death of the cells liningthe gut. Thus, the gut lining is broached and simultaneously thevenomous peptides, often large peptides isolated from venom, can passthrough the gut and sicken or kill the target insect. Surprisingly,insects that have developed resistance to Bt proteins have no defensesand show no resistance at all to even low levels of Bt, when a PFIP likeBt is administered to an insect in combination with CRIP or TMOF, thatis a toxic peptide, but one with properties that do not act like a PFIPSsuch as Bt. We provide data showing that certain combinations ofco-adminstered CRIPS and PFIPS can provide more than double the killingand stopping power than would be expected from similar concentrationapplications of either a CRIP OR PFIPS applied individually.

Examples of a PFIP include the cry and VIP proteins from Bt organisms.Bt proteins like the cry proteins disrupt the insect gut membraneallowing for adventitious infection (sepsis) of the insect by gut flora.In the absence of gut microbes, Bt is not insecticidal. Broderick,Nichole PNAS Vol. 103, No. 41 (2006). Hence one would expect that themechanism shown to cause Bt mortality (infection) would be mitigated inthose insects showing Bt resistance, and it is mitigated in thoseinsects. Bt resistant insects show little gut disruption even when fedhigh levels of Bt proteins, like cry. What we have surprisinglydiscovered is that somehow even though these insects guts no longerdisplay the dramatic effects of Bt on the gut, that is they are trulyresistant, when they are exposed to insecticidal peptides of a certaintype, like the CRIPS and TMOF which have a very different mode of actionthan PFIPS like Bt, then these very resistant insects have no resistancewhat so ever. The disappearance of resistance in a “Bt resistant” insectis surprising, and we show this happens, with our data, in the examplesprovided herein. This result was completely unexpected. Now however weunderstand, and we can use this knowledge to explain how sublethalamounts of a PFIP protein like Bt, can be “converted” into a lethalcocktail such that if two (2) or more sublethal amounts of insecticidalprotein are co-administered, then the combination of proteins becomeslethal to insects which are otherwise thought to be too large, or tooresistant to be susceptible to toxic peptides.

It is surprising that insect resistance to PFIPs alone does not conferresistance to the combination of PFIPS with CRIPS and or TMOF. Becauseof the mechanism of action of the PFIPS one would expect that the PFIP,like a Bt protein, would no longer contribute to the toxic effects ofthe combination of PFIPS with CRIPS and or TMOF. Instead the oppositehappens and the combination has a greater than expected level ofactivity as shown with our data.

Insects have developed resistance to Bt. Attempts to combat thisresistance have resulted in the use of many different subtypes of Bt. Weteach here that insect resistance can be overcome by co-application ofvenom peptides. Since the most common mode of resistance (mode 1, priorref) Pence, R. J. “The antimetabolite imidazole as a pesticide.”California Agric. 1965, 13-15. is down regulation of Bt receptors thatline the gut, one would expect insect resistance would be maintained inBt resistant insects because the number of receptors is insufficient torender the insect vulnerable to sepsis by gut flora. What we havediscovered and believe, and our data supports our theory in dramaticfashion (see examples below), is that even with Bt resistant insectsthere remains sufficient membrane abnormalities that exposure to evenlow levels of Bt, when combined with certain small a “toxic”insecticidial peptides, having a different type of mode of action thanBt, will surprisingly cause Bt resistant insects to stop feeding or die,We believe this is because the gut lining is still disrupted in theseresistant insects, just enough, enough to allow the allow passage of themuch smaller venom peptides characteristic of either CRIP and TMOF typesof insectidical peptides.

In this document we do not consider TMOF peptides or Trypsin modulatingoostatic factor (TMOF) peptides which have been identified as apotential larvicides, see D. Borovsky, Journal of Experimental Biology206, 3869-3875, to be a CRIP type of insecticidal peptide. We define aCRIP peptide as one with various cysteines according to our definitionsherein. TMOF peptides does not fit motif that we describe as a CRIPpeptide. Please see the definition section toward the beginning of thesedocuments for a definition of CRIP and TMOF. We discuss combining CRIPand or TMOF type of proteins with a different type of protein wedescribe as PFIPS.

PFIPS are Pore Forming Insecticidal Proteins which are also defined inthe definition section. One example of one type of PFIP are variousproteins of the widely used group of proteins derived from Bt, such ascry, cyt and VIP. These are effective insecticides used for cropprotection in the form of both plant incorporated protectants and foliarsprays. Commercial formulations of such Bt proteins are widely used tocontrol insects at the larval stage.

In contrast to PFIPS, CRIPS such as Inhibitory cysteine knot or ICKpeptides are very different group of peptides that also haveinsecticidal activity, but they act with a very different mode ofaction. In this document there is no overlap of a PFIP protein with aCRIP protein, the two groups are separate and distinct. ICK peptides andeven Non-ICK peptides are both considered CRIPS in this document. CRIPSare often toxic to naturally occurring biological target species,usually insects or arachnids of some type. Often CRIP peptides can havearthropod origins such as the venoms of scorpions or spiders, this venomorigin is very common with ICKs. CRIP may be delivered to theirphysiological site of action in various ways, for example by deliveringthe toxin directly to the insect's gut or internal organs by injection,by application to an insect locus and uptake from surface contact, or byinducing the insect to consume the toxin from its food, for example aninsect feeding upon a transgenic plant.

The peptides described herein may be formulated as either appliedproducts or through transgenic plants face challenges. It can bedifficult to successfully produce such peptides on a commercial scale,with reproducible peptide formation and folding. Cost controls can bechallenging. The wide variety, unique properties and special nature ofpeptides, combined with the huge variety of possible productiontechniques present an overwhelming number of approaches to peptideproduction. Commercial products have their own significant challenges.Peptides are often unstable when applied in the environment of a crop.UV irradiation and other factors can cause Bt insecticides to decayrapidly in the environment, often in as little as a few hours. Further,commercial effectiveness can change. Both Bt spray on products and thetransgenic Bt proteins used as plant incorporated protectant faceemerging insect resistance.

A product is needed that enhances the acute activity, improvesresistance performance, or extends the duration of action in order toincrease insect control and crop protection.

Here we present combinations of Bt Protein and ICK and TMOF peptides invarious combinations. We describe examples of these novel combinations.The new combinations, products, methods, and their formulation and usesthereof are described and claimed herein.

Cysteine Rich Insecticidal Peptides (CRIPS) in Synergistic Combinations

Cysteine rich insecticidal peptides (CRIPS) are peptides rich incysteine which form disulfide bonds. The cysteine-cysteine disulfidebonds play a significant role in the toxicity of these insecticidalpeptides which are exemplified by both inhibitory cysteine knot or ICKpeptides and by examples of toxic peptides with disulfide bonds that arenot considered ICK peptides (non-ICK CRIPS) such as peptides from thesea anemone, like Av2 and Av3 peptides. These cysteine-cysteinedisulfide bonds stabilized toxic peptides (CRIPS) can have remarkablestability when exposed to the environment. Many ICK peptides areisolated from venomous animals such as spiders, scorpions, and snakesand are toxic to insects. TMOF peptides are known to have larvicidalactivity. Av2 and Av3 peptides are isolated from sea anemones. We alsodescribe a different group of peptides that act on the lining of theinsect gut. We call these PFIPS for Pore Forming Insecticidal Proteins.Most well known examples of a PFIPS are the Bt proteins, well knownbecause of their specific pesticidal activities and commercialapplications. Surprisingly, we discovered that, when the combination ofthese peptides, PFIPS and CRIPS are combined and administered so theyact together in the gut (co-administration of the combination notrequired only the combination of the activity in the gut is needed) theybecome highly effective at controlling insects. For example, one of thepreferred combinations would be to combine a Bt protein with an ICKpeptides, or sea anemone peptides they create a highly effectiveinsecticide with a potency much greater than one would expect.

We describe an insecticidal combination peptide composition comprisingboth a PFIP (Pore Forming Insecticidal Proteins) in combination with aeither a CRIP and/or a TMOF type of insecticidal protein. Note that CRIPincludes such insecticidal proteins as ICK (Inhibitor Cystine Knot)peptides, and Non-ICK proteins but TMOF peptides are not considered CRIPproteins.

Section I. The ICK Motif Peptides or ICK Peptides.

“ICK motif,” “ICK motif protein,” “inhibitor cystine knot motif,” “Toxicinsect ICK peptides” or “ICK peptides” means a 16 to 60 amino acidpeptide with at least 6 half-cystine core amino acids having threedisulfide bridges, wherein the 3 disulfide bridges are covalent bondsand of the six half-cystine residues the covalent disulfide bonds arebetween the first and fourth, the second and fifth, and the third andsixth half-cystines, of the six core half-cystine amino acids startingfrom the N-terminal amino acid. The ICK motif also comprises abeta-hairpin secondary structure, normally composed of residues situatedbetween the fourth and sixth core half-cystines of the motif, thehairpin being stabilized by the structural crosslinking provided by themotif's three disulfide bonds. Note that additional cysteine/cystine orhalf-cystine amino acids may be present within the inhibitor cystineknot motif.

This motif is common in peptides isolated from the venom of numerousspecies. Invertebrate species include spiders and scorpions, otherexamples are numerous, even snake venom has been known to have peptideshaving the ICK motif. Specific examples of insecticidal ICK peptides arethe “U peptides” disclosed herein and in published patents and patentapplications and its homologies, which have an origin from the venoms ofAustralian Funnel-web spiders. These proteins are also referred to asACTX peptides from the Australian Blue Mountains Funnel-web Spider, butthe procedures described herein are useful and may be applied to anyprotein with the ICK motif. The following documents are incorporated byreference in the United States in their entirety, are known to oneskilled in the art, and have all been published.

The purified peptide,iberiotoxin, an inhibitor of the Ca2+-activated K+ channel, fromscorpion (Buthus tamulus) venom was disclosed in Galvez, A. et al.“Purification and characterization of a unique, potent, peptidyl probefor the high conductance calcium-activated potassium channel from venomof the scorpion Buthus tamulus” Journal of Biological Chemistry, 1990Jul. 5; 265(19): 11083-90. The purified peptide, charybdotoxin, aninhibitor of the Ca2+-activated K+ channel, from the venom of thescorpion Leiurus quinquestriatus was disclosed in Gimenez-Gallego, G. etal. “Purification, sequence, and model structure of charybdotoxin, apotent selective inhibitor of calcium-activated potassium channels” ProcNatl Acad Sci, 1988 May; 85(10): 3329-3333. From these and otherpublications, one skilled in the art should be able to readily identifyproteins and peptides having what we describe as the ICK motif, ICKmotif protein or the “inhibitor cystine knot motif.”

The ICK motif protein can be any protein with the ICK motif and isbetween 16 and 60 amino acids in length, with at least 6 cysteineresidues that create covalent cross-linking disulfide bonds in theproper order. Some ICK motif peptides have between 26-60 amino acids inlength. Some ICK motif proteins are between 16-48 amino acids in length.Some ICK motif proteins are between 26-48 amino acids in length. SomeICK motif proteins are between 30-44 amino acids in length. ICK motifproteins with natural insecticidal activity are preferred but ICK motifproteins with other types of activity such as salt and frost resistanceare known to those skilled in the art and are claimed herein. Examplesof insecticidal ICK motif proteins include the ACTX peptides and genes,and including all of the peptides and their coding genes known as Magi6.

Examples of insecticidal ICK motif proteins include the ACTX peptidesand genes and include all of the peptides and their coding genes asdescribed in the references provided above and herein. Specific examplesof ICK motif proteins and peptides disclosed for purposes of providingexamples and not intended to be limiting in any way, are the peptidesand their homologies as described above, and in particular peptides andnucleotides which originate from the venoms of Australian Funnel-webspiders.

The U peptides from the Australian Funnel Web Spider, genus Atrax andHadronyche are particularly suitable and work well when placed incombination according to the methods, procedures or processes describedby this invention. Examples of such suitable peptides tested and withdata are provided herein. The following species are also specificallyknown to carry toxic ICK peptides suitable for being made special by theprocess of this invention. The following species are specifically named:Atrax formidabillis, Atrax infensus, Atrax robustus, Hadronyche infensa,Hadronyche versuta. Any toxic ICK peptides derived from any of the genuslisted above and/or genus species and homologous to the U peptide aresuitable for being made special according to the process in thisinvention.

The Examples in this specification are not intended to, and should notbe used to limit the invention, they are provided only to illustrate theinvention.

As noted above, many peptides are suitable candidates for combinationswith Bt protein. The sequences noted above, below and in the sequencelisting are especially suitable peptides that can be made special, andsome of these have been made special according to this invention withthe results shown in the examples below.

Examples of toxic ICK insect peptides are well known and can be found innumerous references. They can be identified by their peptidic nature andtheir activity, usually oral or injection insecticidal activity. Here weprovide a few examples to better illustrate and describe the invention,but the invention is not limited to these examples. All of theseexamples and others not shown here are descriptive of new materials,described and claimed here for the first time.

Toxic ICK insect peptides are peptides of greater than 5 amino acidresidues and less than 3,000 amino acid residues. They range inmolecular weight from about 550 Da to about 350,000 Da. Toxic ICK insectpeptides have some type of insecticidal activity. Typically they showactivity when injected into insects but most do not have significantactivity when applied to an insect topically. The insecticidal activityof toxic ICK insect peptides is measured in a variety of ways. Commonmethods of measurement are widely known to those skilled in the art.Such methods include, but are not limited to determination of medianresponse doses (e.g., LD₅₀, PD₅₀, LC₅₀, ED₅₀) by fitting ofdose-response plots based on scoring various parameters such as:paralysis, mortality, failure to gain weight, etc. Measurements can bemade for cohorts of insects exposed to various doses of the insecticidalformulation in question. Analysis of the data can be made by creatingcurves defined by probit analysis and/or the Hill Equation, etc. In suchcases, doses would be administered by hypodermic injection, byhyperbaric infusion, by presentation of the insecticidal formulation aspart of a sample of food or bait, etc.

Toxic ICK insect peptides or ICK peptides are defined here as allpeptides shown to be insecticidal upon delivery to insects either byhypodermic injection, hyperbaric infusion, or upon per os delivery to aninsect (i.e., by ingestion as part of a sample of food presented to theinsect). This class of peptides thus comprises, but is not limited to,many peptides produced naturally as components of the venoms of spiders,mites, scorpions, snakes, snails, etc. This class also comprises, but isnot limited to, various peptides produced by plants (e.g., variouslectins, ribosome inactivating proteins, and cysteine proteases), andvarious peptides produced by entomopathogenic microbes (e.g. the Cry1/Btprotein family of proteins produced by various Bacillus species.)

The insecticidal peptides may be selected from insecticidal venom, forexample the venom of a spider. The spider may be an Australian funnelweb spider. The peptides from may be from the genus of Atrax orHadronyche, including U-ACTX-Hv1a and its analogs. Specific peptideexamples from spiders are described in the sequence listing providedherein. These peptides can be combined with Bt protein using theprocedures described herein.

Section III. Bt Proteins

Bt are the initials for a bacteria called Bacillus thuringiensis. The Btbacteria produces a family of peptides that are toxic to many insects.The Bt toxic peptides are well known for their ability to produceparasporal crystalline protein inclusions (usually referred to ascrystals) that fall under two major classes of toxins; cytolysins (Cyt)and crystal Bt proteins (Cry). Since the cloning and sequencing of thefirst crystal proteins genes in the early-1980s, may others have beencharacterized and are now classified according to the nomenclature ofCrickmore et al. (1998). Generally Cyt proteins are toxic towards theinsect orders Coleoptera (beetles) and Diptera (flies), and Cry proteinstarget Lepidopterans (moths and butterflies). Cry proteins bind tospecific receptors on the membranes of mid-gut (epithelial) cellsresulting in rupture of those cells. If a Cry protein cannot find aspecific receptor on the epithelial cell to which it can bind, then itis not toxic. Bt strains can have different complements of Cyt and Cryproteins, thus defining their host ranges. The genes encoding many Cryproteins have been identified.

Currently there are four main pathotypes of insecticidal Bt parasporalpeptides based on order specificity: Lepidotera-specific (CryI, nowCry1), Coleoptera-specific (CryIII, now Cry3), Diptera-specific (CryIV,now Cry4, Cry10, Cry11; and CytA, now Cyt1A), and CryII (Now Cry2), theonly family known at that time to have dual (Lepidoptera and Diptera)specificity. Cross-order activity is now apparent in many cases.

The nomenclature assigns holotype sequences a unique name whichincorporates ranks based on the degree of divergence, with theboundaries between the primary (Arabic numeral), secondary (uppercaseletter), and tertiary (lower case letter) rank representingapproximately 95%, 78% and 45% identities. A fourth rank (another Arabicnumber) is used to indicate independent isolations of holotype toxingenes with sequences that are identical or differ only slightly.Currently, the nomenclature distinguishes 174 holotype sequences thatare grouping in 55 cry and 2 cyt families (Crickmore, N., Zeigler, D.R., Schnepf, E., Van Rie, J., Lereclus, D., Daum, J, Bravo, A., Dean, D.H., B. thuringiensis toxin nomenclature). Any of these crystal proteinsand the genes that produce them may be used to produce a suitable Btrelated toxin for this invention.

Also included in the descriptions of this invention are families ofhighly related crystal proteins produced by other bacteria: Cry16 andCry17 from Clostridium bifermentans (Barloy et al., 1996, 1998), Cry 18from Bacillus popilliae (Zhang et al., 1997), Cry43 from Paenibacilluslentimorbis (Yokoyama et al., 2004) and the binary Cry48/Cry49 producedby Bacillus sphaericus (Jones et al., 2008). Other crystalline orsecreted pesticidal proteins, such as the S-layer proteins (Peña et al.,2006) that are included here are, genetically altered crystal proteins,except those that were modified through single amino acid substitutions(e.g., Lambert et al., 1996). Any of these genes may be used to producea suitable Bt related toxin for this invention.

Examples of Bt

In particular, isolated nucleic acid molecules corresponding to Btprotein nucleic acid sequences are provided. Additionally, amino acidsequences corresponding to the polynucleotides are encompassed. Inparticular, the present invention provides for an isolated nucleic acidmolecule comprising a nucleotide sequence encoding the amino acidsequence shown in US 2009/0099081, published on Apr. 18, 2009, all ofwhich is herein incorporated by reference in its entirety, and allsequences identified by number specifically incorporated by reference.SEQ ID NO: 9, 11, 13, 15, or 18, or a nucleotide sequence set forth inSEQ ID NO:1, 2, 4, 6, 7, 8, 10, 12, 14, 16, or 17, as well as variantsand fragments thereof. Nucleotide sequences that are complementary to anucleotide sequence of the invention, or that hybridize to a sequence ofthe invention are also encompassed.

Nucleotide sequences encoding the proteins of the present inventioninclude the sequence set forth in US 2009/0099081, published on Apr. 18,2009, SEQ ID NO: 1, 2, 4, 6, 7, 8, 10, 12, 14, 16, or 17, and variants,fragments, and complements thereof. By “complement” is intended anucleotide sequence that is sufficiently complementary to a givennucleotide sequence such that it can hybridize to the given nucleotidesequence to thereby form a stable duplex. The corresponding amino acidsequence for the Bt protein encoded by this nucleotide sequence are setforth in SEQ ID NO: 33-533.

Nucleic acid molecules that are fragments of these Bt protein encodingnucleotide sequences are also encompassed by the present invention (forexample, US 2009/0099081, published on Apr. 18, 2009, all of which isherein incorporated by reference in its entirety, and all sequencesidentified by number specifically incorporated by reference. SEQ ID NO:8 is a fragment of SEQ ID NO: 4 and 12; SEQ ID NO: 4 is a fragment ofSEQ ID NO: 2). By “fragment” is intended a portion of the nucleotidesequence encoding a Bt protein. A fragment of a nucleotide sequence mayencode a biologically active portion of a Bt protein, or it may be afragment that can be used as a hybridization probe or PCR primer usingmethods disclosed below. Nucleic acid molecules that are fragments of aBt protein nucleotide sequence comprise at least about 50, 100, 200,300, 400, 500, 600, 700, 800, 900, 1000, 1050, 1100, 1150, 1200, 1250,1300, 1350, 1400, 1450, 1500, 1550, 1600, 1650, 1700, 1750, 1800, 1850,1860, 1870, 1880, 1885 contiguous nucleotides, or up to the number ofnucleotides present in a full-length Bt-protein encoding nucleotidesequence disclosed herein (for example, 1890 nucleotides for US2009/0099081, published on Apr. 18, 2009, Here these are provided as SEQID NO: 1 and 2, 1806 nucleotides for SEQ ID NO: 4, 1743 nucleotides forSEQ ID NO: 6, 7, 8, and 16, 1809 nucleotides for SEQ ID NO: 10, and 1752nucleotides for SEQ ID NO: 12 and 14, in the sequence listing) dependingupon the intended use. By “contiguous” nucleotides is intendednucleotide residues that are immediately adjacent to one another.Fragments of the nucleotide sequences of the present invention willencode protein fragments that retain the biological activity of the Btprotein protein and, hence, retain pesticidal activity. By “retainsactivity” is intended that the fragment will have at least about 30%, atleast about 50%, at least about 70%, 80%, 90%, 95% or higher of thepesticidal activity of the Bt protein. Methods for measuring pesticidalactivity are well known in the art. See, for example, Czapla and Lang(1990) J. Econ. Entomol. 83:2480-2485; Andrews et al. (1988) Biochem.

No. 5,743,477, all of which are herein incorporated byreference in its entirety, and all sequences identified by numberspecifically incorporated by reference.

A fragment of a Bt protein encoding nucleotide sequence that encodes abiologically active portion of a protein of the invention will encode atleast about 15, 25, 30, 50, 75, 100, 125, 150, 175, 200, 250, 300, 350,400, 450, 500, 550, 560, 570, 575, 580, 585, 590, 595, 600 contiguousamino acids, or up to the total number of amino acids present in afull-length Bt protein protein of the invention (for example, 580 aminoacids for SEQ ID NO: 41, 602 amino acids for SEQ ID NO: 43, and 583amino acids for SEQ ID NO: 45 and 47).

Preferred Bt protein proteins of the present invention are encoded by anucleotide sequence sufficiently identical to the nucleotide sequence ofUS 2009/0099081, published on Apr. 18, 2009, all of which is hereinincorporated by reference in its entirety, and all sequences identifiedby number specifically incorporated by reference, sequences 1, 2, 4, 6,7, 8, 10, 12, 14, 16, or 17. By “sufficiently identical” is intended anamino acid or nucleotide sequence that has at least about 60% or 65%sequence identity, about 70% or 75% sequence identity, about 80% or 85%sequence identity, about 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%,99% or greater sequence identity compared to a reference sequence usingone of the alignment programs described herein using standardparameters. One of skill in the art will recognize that these values canbe appropriately adjusted to determine corresponding identity ofproteins encoded by two nucleotide sequences by taking into accountcodon degeneracy, amino acid similarity, reading frame positioning, andthe like.

The invention also encompasses variant nucleic acid molecules (forexample, US 2009/0099081, published on Apr. 18, 2009, all of which isherein incorporated by reference in its entirety, and all sequencesidentified by number specifically incorporated by reference, sequence 2is a variant of sequences 1; sequence 7 and 8 are variants of sequences6; sequence 10 is a variant of sequence 4 and 12; and sequence 14 is avariant of sequence 12). “Variants” of the Bt protein encodingnucleotide sequences include those sequences that encode the Bt proteindisclosed herein but that differ conservatively because of thedegeneracy of the genetic code as well as those that are sufficientlyidentical as discussed above.

Naturally occurring allelic variants can be identified with the use ofwell-known molecular biology techniques, such as polymerase chainreaction (PCR) and hybridization techniques as outlined below. Variantnucleotide sequences also include synthetically derived nucleotidesequences that have been generated, for example, by using site-directedmutagenesis but which still encode the Bt protein proteins disclosed inthe present invention as discussed below. Variant proteins encompassedby the present invention are biologically active, that is they continueto possess the desired biological activity of the native protein, thatis, retaining pesticidal activity. By “retains activity” is intendedthat the variant will have at least about 30%, at least about 50%, atleast about 70%, or at least about 80% of the pesticidal activity of thenative protein. Methods for measuring pesticidal activity are well knownin the art. See, for example, Czapla and Lang (1990) J. Econ. Entomol.83: 2480-2485; Andrews et al. (1988) Biochem.

Section IV. Pesticide Compositions and Increasing Plant Yields

The active ingredients of the present invention are normally applied inthe form of compositions and can be applied to the crop area or plant tobe treated, simultaneously or in succession, with other compounds. Thesecompounds can be fertilizers, weed killers, cryoprotectants,surfactants, detergents, pesticidal soaps, dormant oils, polymers,and/or time-release or biodegradable carrier formulations that permitlong-term dosing of a target area following a single application of theformulation. They can also be selective herbicides, chemicalinsecticides, virucides, microbicides, amoebicides, pesticides,fungicides, bacteriocides, nematocides, molluscicides or mixtures ofseveral of these preparations, if desired, together with furtheragriculturally acceptable carriers, surfactants or application-promotingadjuvants customarily employed in the art of formulation. Suitablecarriers and adjuvants can be solid or liquid and correspond to thesubstances ordinarily employed in formulation technology, e.g. naturalor regenerated mineral substances, solvents, dispersants, wettingagents, tackifiers, binders or fertilizers. Likewise the formulationsmay be prepared into edible “baits” or fashioned into pest “traps” topermit feeding or ingestion by a target pest of the pesticidalformulation.

Methods of applying an active ingredient of the present invention or anagrochemical composition of the present invention that contains at leastone of the pesticidal proteins produced by the bacterial strains of thepresent invention include leaf application, seed coating and soilapplication. The number of applications and the rate of applicationdepend on the intensity of infestation by the corresponding pest.

The composition may be formulated as a powder, dust, pellet, granule,spray, emulsion, colloid, solution, or such like, and may be prepared bysuch conventional means as desiccation, lyophilization, homogenation,extraction, filtration, centrifugation, sedimentation, or concentrationof a culture of cells comprising the polypeptide. In all suchcompositions that contain at least one such pesticidal polypeptide, thepolypeptide may be present in a concentration of from about 1% to about99% by weight.

Lepidopteran or coleopteran pests may be killed or reduced in numbers ina given area by the methods of the invention, or may be prophylacticallyapplied to an environmental area to prevent infestation by a susceptiblepest. Preferably the pest ingests, or is contacted with, apesticidally-effective amount of the polypeptide. By“pesticidally-effective amount” is intended an amount of the pesticidethat is able to bring about death to at least one pest, or to noticeablyreduce pest growth, feeding, or normal physiological development. Thisamount will vary depending on such factors as, for example, the specifictarget pests to be controlled, the specific environment, location,plant, crop, or agricultural site to be treated, the environmentalconditions, and the method, rate, concentration, stability, and quantityof application of the pesticidally-effective polypeptide composition.The formulations may also vary with respect to climatic conditions,environmental considerations, and/or frequency of application and/orseverity of pest infestation.

The pesticide compositions described may be made by formulating eitherthe bacterial cell, crystal and/or spore suspension, or isolated proteincomponent with the desired agriculturally-acceptable carrier. Thecompositions may be formulated prior to administration in an appropriatemeans such as lyophilized, freeze-dried, desiccated, or in an aqueouscarrier, medium or suitable diluent, such as saline or other buffer. Theformulated compositions may be in the form of a dust or granularmaterial, or a suspension in oil (vegetable or mineral), or water oroil/water emulsions, or as a wettable powder, or in combination with anyother carrier material suitable for agricultural application. Suitableagricultural carriers can be solid or liquid and are well known in theart. The term “agriculturally-acceptable carrier” covers all adjuvants,inert components, dispersants, surfactants, tackifiers, binders, etc.that are ordinarily used in pesticide formulation technology; these arewell known to those skilled in pesticide formulation. The formulationsmay be mixed with one or more solid or liquid adjuvants and prepared byvarious means, e.g., by homogeneously mixing, blending and/or grindingthe pesticidal composition with suitable adjuvants using conventionalformulation techniques. Suitable formulations and application methodsare described in U.S. Pat. No. 6,468,523, herein incorporated byreference.

Methods for Increasing Plant Yield

Methods for increasing plant yield are provided. The methods compriseintroducing into a plant or plant cell a polynucleotide comprising apesticidal sequence disclosed herein. As defined herein, the “yield” ofthe plant refers to the quality and/or quantity of biomass produced bythe plant. By “biomass” is intended any measured plant product. Anincrease in biomass production is any improvement in the yield of themeasured plant product. Increasing plant yield has several commercialapplications. For example, increasing plant leaf biomass may increasethe yield of leafy vegetables for human or animal consumption.Additionally, increasing leaf biomass can be used to increase productionof plant-derived pharmaceutical or industrial products. An increase inyield can comprise any statistically significant increase including, butnot limited to, at least a 1% increase, at least a 3% increase, at leasta 5% increase, at least a 10% increase, at least a 20% increase, atleast a 30%, at least a 50%, at least a 70%, at least a 100% or agreater increase in yield compared to a plant not expressing thepesticidal sequence.

In specific methods, plant yield is increased as a result of improvedpest resistance of a plant expressing a pesticidal protein disclosedherein. Expression of the pesticidal protein results in a reducedability of a pest to infest or feed on the plant, thus improving plantyield.

Section V. Plant Transformations

Any combination of the principal components ICK motif protein and orTMOF motif protein and Bt protein, can be combined in a PIP. We alsodisclose the addition of ERSP (Endoplasmic Reticulum Signal Peptide) anda translational stabilizing protein and intervening linker in order tocreate a superior PIP (Plant-incorporated protectant) and expressed as aPEP (Plant Expressed Peptide) as long as a minimum of both Bt and ICKmotif protein are used, it is preferred to use these two peptides incombination with ERSP. TMOF motif can also be used with or replacing theICK motif. These compositions can be created, used as a PEP andexpressed as a PIP.

We describe methods to increase the efficacy of the plant expression, toincrease the accumulation of plant expressed proteins and todramatically increase the insecticidal activity of plant expressedproteins. We describe targeting of the ICK motif protein to theEndoplasmic Reticulum (ER) by an Endoplasmic Reticulum Signaling Protein(ERSP) in plants, in order to provide for the correct covalentcross-linking of peptide disulfide bridges which generate the essentialtertiary ICK motif structure required for insecticidal activity. Wefurther describe targeting of the ICK motif protein to the ER by an ERSPin plants, with a translational stabilizing protein domain added inorder to increase the size of the resulting ICK fusion protein whichenhances peptide accumulation in the plant. We further describetargeting of the ICK motif protein to the ER by an ERSP in plants, witha translation stabilizing protein added as above, and with anintervening peptide sequence added, the latter of which allows forpotential cleavage and the recovery of the active form of the ICK motifprotein having insecticidal activity.

This invention describes the ICK motif proteins with insecticidalactivity that are plant expressed and which can successfully protect aplant or crop from insect damage. The methods taught herein will enablepeptides to not only be expressed in a plant but to be expressed andfolded properly, so that they retain their insecticidal activity evenafter expression in the plant

We describe how the open reading frame (ORF) of a target peptide, suchas an ICK motif peptide, must be modified in order for the desiredbiological activity to remain after plant expression of the ICK motifpeptide. In one embodiment we describe a Plant Incorporated Protectant,or PIP, that expresses an active insecticidal protein. The PIPinsecticidal protein is comprised of an Endoplasmic Reticulum SignalPeptide (ERSP) operably linked to a Cysteine Rich Insecticidal Peptide(CRIP) or Inhibitor Cystine knot (ICK) motif protein, wherein the ERSPis the N-terminal of the linked ERSP+ICK motif protein. The PIPinsecticidal protein is then incorporated into a plant of choice to giveinsect resistance to the plant. The plant cells will express andaccumulate the properly folded ICK motif insecticidal protein. When aninsect consumes the plant cells, the properly folded ICK motifinsecticidal protein will be delivered inside the insect where it willhave insecticidal activity and cause the insect either to slow or tostop its feeding, slow its movements, and slow or stop reproduction, allof which provides protection for the plant from insect damage.

We describe transient expression systems to express various plantexpression cassettes. One expressed transgene we use is GreenFluorescent Protein or GFP, which is detectable visually when excited byUV light. The GFP transient expression system we used for the evaluationof plant transgenic proteins is for all practical purposes-equivalent touse of a stable transgenic plant system for these types of evaluations.

The CRIP, ICK, TMOF, Sea Anemone Motif can be Linked to the ERSP.

For the ICK motif insecticidal protein to be properly folded when it isexpressed from a transgenic plant, it must have an ERSP fused in framewith the ICK motif insecticidal protein. This can also be done with aTMOF motif. This can be accomplished in several ways. See FIGS. 1, 2 and3. The protein should be routed through the ER where the correctcovalent bond connections for proper disulfide bond formation areformed. Without wishing to be bound by theory, we believe the ER routingresults in the correct tertiary structure of the ICK motif protein. Itis commonly postulated that such routing is achieved by a cellularcomponent called a signal-recognition particle: the signal-recognitionparticle binds to the ribosome translating the protein, it pausestranslation, and it transports the ribosome/mRNA complex to atranslocator pore in the ER, where the ribosome then continues thetranslation and threads the resulting protein into the ER. Within the ERthe ERSP is cleaved and the protein is acted upon by posttranslationalmodification processes in the ER. Once such process involves proteindisulfide isomerases, a class of proteins that catalyse the formation ofdisulfide bonds. Without any additional retention protein signals, theprotein is transported through the ER to the golgi apparatus, where itis finally secreted outside the plasma membrane and into the apoplasticspace. Without wishing to be bound by theory, we think proteins, such asinsecticidal proteins, that have an ICK motif, need to be routed throughthe ER, in order for the proteins to have correct disulfide bondformation, if they are expressed in plants.

The ERSP (Endoplasmic Reticulum Signaling Protein).

In addition to the text below, see Part I-I (The EERSP or ersp componentof the PEPs.

The ERSP is the N-terminal region of the ERSP+ICK motif protein complexand the ERSP portion is composed of about 3 to 60 amino acids. In someembodiments it is 5 to 50 amino acids. In some embodiments it is 10 to40 amino acids but most often is composed of 15 to 20; 20 to 25; or 25to 30 amino acids. The ERSP is a signal peptide so called because itdirects the transport of a protein. Signal peptides may also be calledtargeting signals, signal sequences, transit peptides, or localizationsignals. The signal peptides for ER targeting are often 15 to 30 aminoacid residues in length and have a tripartite organization, comprised ofa core of hydrophobic residues flanked by a positively chargedaminoterminal and a polar, but uncharged carboxyterminal region. See:Zimmermann, Richard; Eyrisch, Susanne; Ahmad, Mazen and Helms, Volkhard:“Protein translocation across the ER membrane” Biochimica et BiohysicaActa 1808 (2011) 912-924, Elsevier.

About half and often more of the ERSP is usually comprised ofhydrophobic amino acids, but the percentage of amino acids in an ERSPthat are hydrophobic can vary. Without wishing to be bound by any theoryof how the invention works, we think the hydrophobic amino acids stickin the membrane of the ER after translation and this allows the signalpeptide peptidase to cleave the ERSP off of the translated protein,releasing the ICK motif protein into the ER. Many ERSPs are known. Manyplant ERSPs are known. It is NOT required that the ERSP be derived froma plant ERSP, non-plant ERSPs will work with the procedures describedherein. Many plant ERSPs are however well known and we describe someplant derived ERSPs here. BAAS, for example, is derived from the plant,Hordeum vulgare.

One example of a ERSP used here is BAAS, the sequence of BAAS is MANKHLSLSL FLVLL GLSAS LASG (SEQ ID NO: 1035-one letter code)

This peptide, named “BAAS” is cleaved from the ICK motif upon theprotein's translation into the ER. The molecular weight is 2442.94Daltons. FIGS. 1-3 shows a representation of a ICK motif protein linkedto an ERSP. These figures could equally represent a TMOF motif proteinlinked to an ERSP.

The Translational Stabilizing Protein.

In addition to the text below, see Part I-III (The translationalstabilizing protein component, STA or sta.

The procedures described above refer to providing a ERSP+CRIP whereERSP+CRIP could be ERSP+ICK, ERSP+Non-ICK, ERSP+Av (SEA ANOMONE) or theprocedures could refer to ERSP+TMOF, or they could refer to ERSP+CRIPand a TMOF sufficient to make a plant produce properly folded peptides.We also suggest that in order to more fully protect a plant from someinsects, more than just proper folding is sometimes needed. With aproperly constructed expression cassette, a plant can be induced to makeand accumulate even greater amounts of toxic peptide. When a plantaccumulates greater amounts of properly folded toxic CRIP or TMOFpeptides it can more easily resist or kill the insects that attack andeat the plants. One way to increase the insecticidal activity of the PIPis with translational stabilizing proteins. The translationalstabilizing protein can be used to significantly increase theaccumulation of the toxic peptide in the plant and thus the potency ofthe PIP, especially when the PIP has a translational stabilizing proteinof its own. The procedures described herein can provide for theaccumulation in the plant of large amounts of the now properly foldedtransgenic plant proteins. Transgenic plants expressing both an ICKmotif insecticidal protein and a translational stabilizing protein,demonstrate dramatically improved accumulation of toxic ICK peptidesover systems without a translational stabilizing protein. RepresentativePIPs with a translational stabilizing protein are described herein.

Experiments comparing plant expressed peptides both with and without atranslational stabilizing protein show dramatic differences. The proteinexpression of an ICK-motif protein without a translational stabilizingprotein can be very low. When a translational stabilizing protein isfused to the ICK-motif protein, there are higher levels of detectableaccumulation. The translational stabilizing protein can be a domain ofanother protein or it can comprise an entire protein sequence. Thetranslational stabilizing protein is a protein with sufficient tertiarystructure that it can accumulate in a cell without being targeted by thecellular process of protein degradation. The protein can be between 5and 50aa (eg another ICK-motif protein), 50 to 250aa (GNA), 250 to 750aa(eg chitinase) and 750 to 1500aa (eg enhancin).

The translational stabilizing protein, (or protein domain) can containproteins that have no useful characteristics other than translationstabilization, or they can have other useful traits in addition totranslational stabilization. One embodiment of the translationstabilization protein can be multiple ICK-motif proteins in tandem.Useful traits can include: additional insecticidal activity, such asactivity that is destructive to the peritrophic membrane, activity thatis destructive to the gut wall, and/or activity that actively transportsthe ICK motif protein across the gut wall. One embodiment of thetranslational stabilizing protein can be a polymer of fusions proteinsinvolving ICK motif proteins. One embodiment of the translationalstabilizing protein can be a polymer of fusions proteins involving TMOFmotif proteins. A specific example of a translational stabilizingprotein is provided here to illustrate the use of a translationalstabilizing protein. The example is not intended to limit the disclosureor claims in any way. Useful translational stabilizing proteins are wellknown in the art, and any proteins of this type could be used asdisclosed herein. Procedures for evaluating and testing production ofpeptides are both known in the art and described herein. One example ofone translational stabilizing protein is SEQ ID NO:1036, one lettercode, as follows:

This invention also incorporates an intervening linker between ICK motifprotein and the translational stabilizing protein. The interveninglinker is between 1 and 30 amino acids. It can have either no cleavagesites or a protease cleavage site specific to serine-, threonine-,cysteine-, and aspartate proteases or metalloproteases.

Other Plant Transformations are More Well Known.

Methods of the invention involve introducing a nucleotide construct intoa plant. By “introducing” is intended to present to the plant thenucleotide construct in such a manner that the construct gains access tothe interior of a cell of the plant. The methods of the invention do notrequire that a particular method for introducing a nucleotide constructto a plant is used, only that the nucleotide construct gains access tothe interior of at least one cell of the plant. Methods for introducingnucleotide constructs into plants are known in the art including, butnot limited to, stable transformation methods, transient transformationmethods, and virus-mediated methods.

By “plant” is intended whole plants, plant organs (e.g., leaves, stems,roots, etc.), seeds, plant cells, propagules, embryos and progeny of thesame. Plant cells can be differentiated or undifferentiated (e.g.callus, suspension culture cells, protoplasts, leaf cells, root cells,phloem cells, pollen).

“Transgenic plants” or “transformed plants” or “stably transformed”plants or cells or tissues refers to plants that have incorporated orintegrated exogenous nucleic acid sequences or DNA fragments into theplant cell. These nucleic acid sequences include those that areexogenous, or not present in the untransformed plant cell, as well asthose that may be endogenous, or present in the untransformed plantcell. “Heterologous” generally refers to the nucleic acid sequences thatare not endogenous to the cell or part of the native genome in whichthey are present, and have been added to the cell by infection,transfection, microinjection, electroporation, microprojection, or thelike.

Transformation of plant cells can be accomplished by one of severaltechniques known in the art. The Bt-protein gene of the invention may bemodified to obtain or enhance expression in plant cells. Typically aconstruct that expresses such a protein would contain a promoter todrive transcription of the gene, as well as a 3′ untranslated region toallow transcription termination and polyadenylation. The organization ofsuch constructs is well known in the art. In some instances, it may beuseful to engineer the gene such that the resulting peptide is secreted,or otherwise targeted within the plant cell. For example, the gene canbe engineered to contain a signal peptide to facilitate transfer of thepeptide to the endoplasmic reticulum. It may also be preferable toengineer the plant expression cassette to contain an intron, such thatmRNA processing of the intron is required for expression.

Typically this “plant expression cassette” will be inserted into a“plant transformation vector”. This plant transformation vector may becomprised of one or more DNA vectors needed for achieving planttransformation. For example, it is a common practice in the art toutilize plant transformation vectors that are comprised of more than onecontiguous DNA segment. These vectors are often referred to in the artas “binary vectors”. Binary vectors as well as vectors with helperplasmids are most often used for Agrobacterium-mediated transformation,where the size and complexity of DNA segments needed to achieveefficient transformation is quite large, and it is advantageous toseparate functions onto separate DNA molecules. Binary vectors typicallycontain a plasmid vector that contains the cis-acting sequences requiredfor T-DNA transfer (such as left border and right border), a selectablemarker that is engineered to be capable of expression in a plant cell,and a “gene of interest” (a gene engineered to be capable of expressionin a plant cell for which generation of transgenic plants is desired).Also present on this plasmid vector are sequences required for bacterialreplication. The cis-acting sequences are arranged in a fashion to allowefficient transfer into plant cells and expression therein. For example,the selectable marker gene and the Bt-protein are located between theleft and right borders. Often a second plasmid vector contains thetrans-acting factors that mediate T-DNA transfer from Agrobacterium toplant cells. This plasmid often contains the virulence functions (Virgenes) that allow infection of plant cells by Agrobacterium, andtransfer of DNA by cleavage at border sequences and vir-mediated DNAtransfer, as is understood in the art (Hellens and Mullineaux (2000)Trends in Plant Science 5:446-451). Several types of Agrobacteriumstrains (e.g. LBA4404, GV3101, EHA101, EHA105, etc.) can be used forplant transformation. The second plasmid vector is not necessary fortransforming the plants by other methods such as microprojection,microinjection, electroporation, polyethylene glycol, etc.

In general, plant transformation methods involve transferringheterologous DNA into target plant cells (e.g. immature or matureembryos, suspension cultures, undifferentiated callus, protoplasts,etc.), followed by applying a maximum threshold level of appropriateselection (depending on the selectable marker gene) to recover thetransformed plant cells from a group of untransformed cell mass.Explants are typically transferred to a fresh supply of the same mediumand cultured routinely. Subsequently, the transformed cells aredifferentiated into shoots after placing on regeneration mediumsupplemented with a maximum threshold level of selecting agent. Theshoots are then transferred to a selective rooting medium for recoveringrooted shoot or plantlet. The transgenic plantlet then grows into amature plant and produces fertile seeds (e.g. Hiei et al. (1994) ThePlant Journal 6:271-282; Ishida et al. (1996) Nature Biotechnology14:745-750). Explants are typically transferred to a fresh supply of thesame medium and cultured routinely. A general description of thetechniques and methods for generating transgenic plants are found inAyres and Park (1994) Critical Reviews in Plant Science 13:219-239 andBommineni and Jauhar (1997) Maydica 42:107-120. Since the transformedmaterial contains many cells; both transformed and non-transformed cellsare present in any piece of subjected target callus or tissue or groupof cells. The ability to kill non-transformed cells and allowtransformed cells to proliferate results in transformed plant cultures.Often, the ability to remove non-transformed cells is a limitation torapid recovery of transformed plant cells and successful generation oftransgenic plants.

Transformation protocols as well as protocols for introducing nucleotidesequences into plants may vary depending on the type of plant or plantcell, i.e., monocot or dicot, targeted for transformation. Generation oftransgenic plants may be performed by one of several methods, including,but not limited to, microinjection, electroporation, direct genetransfer, introduction of heterologous DNA by Agrobacterium into plantcells (Agrobacterium-mediated transformation), bombardment of plantcells with heterologous foreign DNA adhered to particles, ballisticparticle acceleration, aerosol beam transformation (U.S. PublishedApplication No. 20010026941; U.S. Pat. No. 4,945,050; InternationalPublication No. WO 91/00915; U.S. Published Application No. 2002015066),Lec1 transformation, and various other non-particle direct-mediatedmethods to transfer DNA.

Methods for transformation of chloroplasts are known in the art. See,for example, Svab et al. (1990) Proc. Natl. Acad. Sci. USA 87:8526-8530;Svab and Maliga (1993) Proc. Natl. Acad. Sci. USA 90:913-917; Svab andMaliga (1993) EMBO J. 12:601-606. The method relies on particle gundelivery of DNA containing a selectable marker and targeting of the DNAto the plastid genome through homologous recombination. Additionally,plastid transformation can be accomplished by transactivation of asilent plastid-borne transgene by tissue-preferred expression of anuclear-encoded and plastid-directed RNA polymerase. Such a system hasbeen reported in McBride et al. (1994) Proc. Natl. Acad. Sci. USA91:7301-7305.

Following integration of heterologous foreign DNA into plant cells, onethen applies a maximum threshold level of appropriate selection in themedium to kill the untransformed cells and separate and proliferate theputatively transformed cells that survive from this selection treatmentby transferring regularly to a fresh medium. By continuous passage andchallenge with appropriate selection, one identifies and proliferatesthe cells that are transformed with the plasmid vector. Molecular andbiochemical methods can then be used to confirm the presence of theintegrated heterologous gene of interest into the genome of thetransgenic plant.

The cells that have been transformed may be grown into plants inaccordance with conventional ways. See, for example, McCormick et al.(1986) Plant Cell Reports 5:81-84. These plants may then be grown, andeither pollinated with the same transformed strain or different strains,and the resulting hybrid having constitutive expression of the desiredphenotypic characteristic identified. Two or more generations may begrown to ensure that expression of the desired phenotypic characteristicis stably maintained and inherited and then seeds harvested to ensureexpression of the desired phenotypic characteristic has been achieved.In this manner, the present invention provides transformed seed (alsoreferred to as “transgenic seed”) having a nucleotide construct of theinvention, for example, an expression cassette of the invention, stablyincorporated into their genome.

ICK and TMOF Expression in Plants.

As noted above, there are many alternatives that could be used for thecomponents of ERSP, ICK motif protein, TMOF motif, translationalstabilizing protein and intervening linker.

Evaluation of Plant Transformations

Following introduction of heterologous foreign DNA into plant cells, thetransformation or integration of heterologous gene in the plant genomeis confirmed by various methods such as analysis of nucleic acids,proteins and metabolites associated with the integrated gene.

PCR analysis is a rapid method to screen transformed cells, tissue orshoots for the presence of incorporated gene at the earlier stage beforetransplanting into the soil (Sambrook and Russell (2001) MolecularCloning: A Laboratory Manual. Cold Spring Harbor Laboratory Press, ColdSpring Harbor, N.Y.). PCR is carried out using oligonucleotide primersspecific to the gene of interest or Agrobacterium vector background,etc.

Plant transformation may be confirmed by Southern blot analysis ofgenomic DNA (Sambrook and Russell, 2001, supra). In general, total DNAis extracted from the transformant, digested with appropriaterestriction enzymes, fractionated in an agarose gel and transferred to anitrocellulose or nylon membrane. The membrane or “blot” is then probedwith, for example, radiolabeled .sup.32P target DNA fragment to confirmthe integration of introduced gene into the plant genome according tostandard techniques (Sambrook and Russell, 2001, supra).

In Northern blot analysis, RNA is isolated from specific tissues oftransformant, fractionated in a formaldehyde agarose gel, and blottedonto a nylon filter according to standard procedures that are routinelyused in the art (Sambrook and Russell, 2001, supra). Expression of RNAencoded by the Bt-protein is then tested by hybridizing the filter to aradioactive probe derived from a Bt-protein, by methods known in the art(Sambrook and Russell, 2001, supra).

Western blot, biochemical assays and the like may be carried out on thetransgenic plants to confirm the presence of protein encoded by theBt-protein gene by standard procedures (Sambrook and Russell, 2001,supra) using antibodies that bind to one or more epitopes present on theBt-protein.

Pesticidal Activity in Plants

In another aspect of the invention, one may generate transgenic plantsexpressing a Bt-protein that has pesticidal activity. Methods describedabove by way of example may be utilized to generate transgenic plants,but the manner in which the transgenic plant cells are generated is notcritical to this invention. Methods known or described in the art suchas Agrobacterium-mediated transformation, biolistic transformation, andnon-particle-mediated methods may be used. Plants expressing aBt-protein may be isolated by common methods described in the art, forexample by transformation of callus, selection of transformed callus,and regeneration of fertile plants from such transgenic callus. In suchprocess, one may use any gene as a selectable marker so long as itsexpression in plant cells confers ability to identify or select fortransformed cells.

A number of markers have been developed for use with plant cells, suchas resistance to chloramphenicol, the aminoglycoside G418, hygromycin,or the like. Other genes that encode a product involved in chloroplastmetabolism may also be used as selectable markers. For example, genesthat provide resistance to plant herbicides such as glyphosate,bromoxynil, or imidazolinone may find particular use. Such genes havebeen reported (Stalker et al. (1985) J. Biol. Chem. 263:6310-6314(bromoxynil resistance nitrilase gene); and Sathasivan et al. (1990)Nucl. Acids Res. 18:2188 (AHAS imidazolinone resistance gene).Additionally, the genes disclosed herein are useful as markers to assesstransformation of bacterial or plant cells. Methods for detecting thepresence of a transgene in a plant, plant organ (e.g., leaves, stems,roots, etc.), seed, plant cell, propagule, embryo or progeny of the sameare well known in the art. In one embodiment, the presence of thetransgene is detected by testing for pesticidal activity.

Fertile plants expressing a Bt-protein may be tested for pesticidalactivity, and the plants showing optimal activity selected for furtherbreeding. Methods are available in the art to assay for pest activity.Generally, the protein is mixed and used in feeding assays. See, forexample Marrone et al. (1985) J. of Economic Entomology 78:290-293.

Section VI. Descriptions and Examples of CRIP and Bt ProteinCombinations

The Bt and ICK peptides may inhibit the growth, impair the movement, oreven kill an insect when the combination of toxin is appropriatelydelivered to the locus inhabited by the insect. SDP 1234604, 1234605 and609 are spray-dried powder preparations of hybrid+2-ACTX-Hv1a peptide,here “Hv1a peptide.” The spray-dried Hv1a peptide powders are made fromthe peptide, various excipients and fermentation by-products. The '604and '605 formulations use the same peptide, only the excipients aredifferent. The concentration of the active hybrid peptide was quantifiedat about 26% weight/weight in both the '604 and '605 powders. Theconcentration of the active hybrid peptide was quantified at about 35%weight/weight in the 609 powders. The Hv1a peptide in each powder wasquantified using a C18 rpHPLC methods known by those skilled in the art.

Inhibitory cysteine knot or ICK peptides can have remarkable stabilitywhen exposed to the environment. Many ICK peptides are isolated fromvenomous animals such as spiders, scorpions, and snakes. Bt proteins arewell known because of their specific pesticidal activities.Surprisingly, we have found that, when Bt proteins are selectively mixedwith ICK peptides, the combination of Bt and ICK peptides produces ahighly effective insecticide with a potency much greater than expected.

Example 1 Foliar Bioassay Using SDP 1234604 and 1234605 AgainstSpodoptera exigua on Mud Lakes Farms Romaine Lettuce

Purpose: The purpose of this experiment is designed to determine thepercent mortality which occurs against S. exigua when SDP 1234604 (wpformulation) and 605 (pre-gran formulation) are sprayed against 1st,2nd, 3rd and 4th Instar larvae in a foliar leaf disk bioassay.

Assay Preparation and Treatment Formulation:

S. exigua eggs were received from Benzon Research. Eggs were placed at10° C. in the wine cooler for two days then moved to the VWR LowTemperature Incubator set at 28° C. and 2-30% Relative Humidity on arack under LED lights, until freshly hatched neonate were ˜24 hr old forthe first experiment. Mud Lake Farms Lettuce was received on Jul. 9,2012 and stored at 4° C. in a refrigerator until used. For each instar,larvae were placed on mud lakes farms lettuce after 24 hours in theincubator. Lettuce leaves were cut and placed into a medium squarepolyethylene container and larvae were tapped into the container. After24 hours, larvae were removed from the old lettuce and fresh lettuce wasreplaced so that larvae were not reared on less than superior tissue.This occurred once a day, for three days, until larvae were 96 hoursold. Lettuce leaves were cut into disks using a 2½ inch arch which hasbeen sanitized with 70% ethanol and cleaned to remove any leaf tissuefrom previous assays. Leaf disks were punched on a true bamboo cuttingboard. A very dilute 12 ppm bleach solution ( 1/500th dilution of 6ppthypochlorite {Clorox Bleach} Stock) was used to sanitize the leaf tissuewithout damaging leaf disks before the quadruple rinse. Leaf disks weresubjected to the 12 ppm bleach treatment by placing the cut leaf disk ina 12 ppm solution of bleach in a large rectangular polyethylenecontainer (covered with a lid) and shaking at 3500 rpm on an orbitalshaker for 1.5 minutes. Bleach solution was then drained from the binand leaves were rinsed in bins with dH2O four times to remove residualbleach with slight agitation in diH2O on the orbital shaker. Leaf diskswere placed onto the paper towels and covered with additional papertowels so that they do not dry out. Only the flattest, circular anduniform disks were then hand dried with Kimwipes to remove any remainingwater and placed into labeled Tupperware containers abaxial side up forspraying. During this time, formulations were made (as described in thetable that follows) for the spray solutions of spray dried powders onthe leaf disks in 50 mL Falcon tube being sure to fill tubes withdeionized H2O before adding the precisely massed amount of spray driedpowders. Spraying was performed in the Labconco fume hood in E207starting with the ventral side of the leaf disk. For spraying, a doubleaction, internal mix airbrush (Paasch Airbrush Company, Chicago Ill.)with the airline set at a rate of 200 μL/second (20 psi). Leaf diskswere sprayed in a circular fashion with the airbrush perpendicular tothe leaf surface so that a fine mist covered the entire leaf surfaceevenly (˜3-4 seconds). Between each treatment spray, the cup containingspray solution was rinsed with dH2O to remove any residues from previoustreatments. After spraying, drying was allowed for one hour then diskswere flipped so their adaxial side was now orientated facing up in theTupperware Container and sprayed in the same manner. After spraying theadaxial side, an hour was allowed for drying and leaf disks were placedin labeled petri dishes with 2 90 mm Whatman 3 Qualitative Filter Papers(GE Healthcare UK Limited, Amersham Place Little Chalfont,Buckinghamshire, HP7 9NA, UK) at the bottom that have been wetted with 4mL of diH2O using a Eppendorf Repeater Plus and a 25 mL tip. Petridishes were covered and randomized before ˜7-9 freshly hatched neonatesS. exigua were applied to each leaf disk using a #0 fine haired brush byobtaining a white board and emptying a container of 24, 48, 72 or 96 hrneonates onto it. Plates were sealed with parafilm and placed randomlyon the rack for statistical purposes at 27° C. The assay was scored overthe following day at 18, 24, 40 and 48 hours by observing mortality andnoting any differences between untreated and treated leaves.

FIG. 19 shows the percent mortality results of four experiments recordedfor each experiment at 18, 24, 40 and 48 hours. The non-spray driedcontrol treatment showed the lowest average mortality of any treatments.The majority of insect mortality is observed at the 18 hour scoring andadditional mortality is observed at 40 and 48 hours shown by the 40 and48 hour scoring. Healthy insects have noticeable green, chlorophyll likecolor, fast evasion response when prodded with paint brush and averagegrowth for 48 hours. Percent mortality results of 72 and 96 hour larvaeare significantly reduced compared to the 24 and 48 hour old larvae.Clearly, both Bt protein and Hybrid peptide treatments alone areineffective in controlling older insects.

Example 2

Foliar Bioassay using SDP 1234605 against Spodoptera exigua on Mud LakesFarms Romaine Lettuce.

Purpose: The purpose of this experiment is designed to determine thepercent mortality which occurs against S. exigua when SDP 1234605 issprayed against 72 hour old larvae in a foliar leaf disk bioassay andwhen Dipel DF is ω-sprayed with SDP 1234605.

Assay Preparation and Treatment Formulation: See preparation inExample 1. S. exigua eggs were received from Benzon Research. Petridishes were covered and randomized before ˜7-9 freshly hatched neonatesS. exigua were applied to each leaf disk using a #0 fine haired brush byobtaining a white board and emptying a container of 72 hr old larvaeonto it. Plates were sealed with parafilm and placed randomly on therack for statistical purposes at 27° C. The assay was scored over thefollowing day at 18, 24 and 48 hours by observing mortality and notingany differences between untreated and treated leaves. FIG. 20 shows acolumn graph Example 2 data at 18, 24 and 48 hours. Individually 10parts per thousand (ppt) of Hybrid peptide in formulation '605 and Dipelat 300 parts per million (ppm) show little improvement over either theuntreated control or surfactant mortalities. However, when combined theresultant mortality at 48 hours of 84.4% surprisingly exceeds that whichwould be expected from the additive effects of the individual treatments(29.1%). The synergy of the individual components is at least 2.9 fold(84.4/29.1). It is unexpected that a insecticidal protein that killsthrough sepsis would be synergistic with a insecticidal peptide thatmodulates ion channels in the CNS.

Example 3

We investigated the potential additive and/or synergistic affects ofcombinations of Bacillus thuringiensis (Bt) proteins and the Av2 peptidefrom sea anemones. We used the Bt product: Dipel DF which iscommercially available and commercially available Av2 a toxic seaanemone peptide.

Methods:

Small leaf disks (˜2 cm) were cut into the inner leaves of cabbagepurchased from a local grocery store. Disks were dipped into 4004 oftreatment and placed on 4.25 cm #4 filter disks (Whatman) in the bottomof ˜4.5 cm condiment cups. Four disks were prepared per treatment. 75 μLof water was applied to a second smaller 3.2 cm #1 filter disk (Whatman)atop the larger filter disk. Leaf disks were allowed to dryapproximately ten minutes before adding four 120 hr old Cry1a resistantPlutella xylostella per leaf disk. Condiment cups were sealed withnon-perforated lids. Treatments were placed in the incubator and scoredfor mortality and feeding damage at 24 and 48 hrs. Due to largeconsumption of leaf disks in many treatments, an additional 3.2 cmuntreated leaf disk was added at 24 hr to ensure larval starvation didnot occur.

At 24 and 48 hrs, pictures of leaf disks were taken using an Iphone 4S(Apple Inc.), and saved. Individual leaf disk photos were cropped fromthe group treatment photo and assigned random numbers. Using the programImageJ, leaf area eaten was calculated. The image was opened in imageJand the scale in the photo was set. To set the scale, a known distancein the photo in centimeters (cm) was drawn using the segment line tooland measured in units of pixels. For this experiment, the known diameterof filter paper disk is 1.5 cm for #1 filter disk and 4.5 cm for the #4Whatman Filter disk. Using this known length in cm, pixel units areconverted in the image to centimeters. Once the scale is set, a freehandselection tool is used to draw around the area where leaf tissueremains. This process was repeated for all photos being sure to log areacalculated by image J in the lab notebook. For this experiment thecontrol area of uneaten leaf disk is 2.54 cm² and calculations were madeto determine % area eaten.

Treatments:

150 PPM Dipel DF: 200 μL 300 PPM Dipel DF+200 μL water1 PPT Av2: 0.1 mg Av2 in 100 μL water (combined four vials 1 PPT Av2 fornecessary 400 μL treatments)150 PPM Dipel DF+1PPT Av2: 100 μL 150 PPM Dipel DF was added to 0.1 mgAv2 (four vials were combined for necessary 400 μL treatment)FIG. 21 shows the percent feeding damage resulting from Bt proteinresistant diamondback moth larvae (120 hrs old) on cabbage leaf disks.Scoring at both 24 hours and 48 hours shows significant improvement overtreatment with Dipel alone. While these insects are resistant to Bt,they do still feed to a limited extent without mortality. Thecombination treatment results in significantly improved protection ofthe foliar material. Further, treatment with Av2 alone has no effect onfeeding damage and it is only in combination with the Bt protein thatits effect is made apparent. This is consistent with increasedbioavailability of Av2 made possible by the Bt protein.

Example 4 Foliar Bioassay Using SDP 1234609 and DiPel DF Against onEarthbound Farms Romaine Lettuce

Purpose: The purpose of this experiment is to determine the percentmortality which occurs against Bt resistant (HD-1) P. xylostella whenSDP 1234609 is sprayed against 120 hour old larvae in a foliar leaf diskbioassay and when Dipel DF is co-sprayed with SDP 1234609.

Assay Preparation and Treatment Formulation: See preparation inExample 1. FIG. 22 shows a column graph Example 4 data at 24 and 48hours. Individually 1parts per thousand (ppt) of Hybrid peptide informulation '609 and Dipel at 150 parts per million (ppm) show littleimprovement over either the untreated control or surfactant mortalities.However, when combined the resultant mortality at 48 hours of 62.5%surprisingly exceeds that which would be expected from the additiveeffects of the individual treatments (21.8%). The synergy of theindividual components is at least 2.86 fold (62.5/21.8). Again, it isunexpected that an insecticidal protein that kills through sepsis wouldbe synergistic with a insecticidal peptide that modulates ion channelsin the CNS.
